As we move from single-celled prokaryotic bacteria to new and intriguing organisms (read: Protists), some differences are quite observable and it makes for interesting conversation. Based upon in-class lecture-discussions, your own observations, and the assigned readings--as well as other reading you may have done--how do bacteria & protists compare?
Remember that this week starts the 'Compare & Response' requirement of the blog: that not only must you respond to the above question, you must also respond to at least one other student's posting or comment--if you agree, why? if you disagree, why? . . .and be sure to use evidence and logical reasoning to justify your claim.
Bacteria and Protists are both single celled. Bacteria are prokaryotes (no nucleus and no membrane bound DNA) and have a cell wall. Protists are not only eukaryotes but they have no cell wall. They have a nucleus and membrane bound DNA complexes. This prevents them from staying in one shape like bacteria. They are both in different kingdoms.
ReplyDeleteProtists are eukaryotic, meaning they have a nucleus, a nuclear membrane as well as organelles. Bacteria on the other hand, falls under the category of prokaryotic. Prokaryotic cells, unlike eukaryotic cells, do not have a nuclear membrane or organelles. They are single cellular, this makes them similar to protists or eukaryotic cells because both are single cell organisms. Although the two organisms are single cell, they fall in different kingdoms.
ReplyDeleteBacteria and protists are both single celled organisms. Bacteria are prokaryotes which means that they have no nucleus and no membrane yet they do have a cell wall. Protists on the other hand are eukaryotic which means that they have a nucleus, a nuclear membrane and also, organelles. Although these two organisms are both single cellular organisms they fall into two different kingdoms because they have different traits.

Sami Lyons-
Sami, I agree with you because it is true that protists and bacteria are both single cellular and that they fall into different kingdoms.
Protists and Bacteria have a lot of similarities and differences. The similarities are that they both are single celled organisms, both use Flagella to move, both can be either good or bad and both are microscopic on their own. The differences are that Bacteria have no nucleus, bacteria are smaller than protists, bacteria are ONLY single celled and finally, they are both in different kingdoms.

Sami, I agree as well with what you said especially the part about different kingdoms and bacteria and protists having different traits.

ReplyDeleteAliza White:
Aliza, I totally agree with what you said; especially about the specifics of what traits varied from bacteria to protists.
Prokaryotic bacteria has a nucleus and do not have organelles, membrane , DNA but, is the highest kingdom classification. Protists are eukaryote, has a nucleus, DNA and membrane. The difference is that the prokaryotes are a lot less complex.
ReplyDeleteComment:
ReplyDeleteI agree with emily that they have some similarities and some differences. for example: they both are single celled but prokaryotes do not have organelles.
Protists and bacteria have a common similarity that they are single celled organisms, and use flagella. Protists are eukaryotic, they have organelles and a nucleus. Bacteria are prokaryotic meaning they have no nuclear membrane, and no organelles. Eukaryotic refers to animals, plants, and everything besides bacteria.
ReplyDeleteComment:
ReplyDeleteI agree with Aliza, while they are both single celled organisms, they fall under different kingdoms.
Comment:
ReplyDeleteEmily, I really like the point you made about how they are microscopic on their own, and agree with all the statements you made about their similarities.
Although Protists and Bacteria are both single cell organisms. Protists are eukaryotic which means it has a nucleus, organelles, and DNA. Bacteria are prokaryotic that means that they have no nucleus, organelle, and DNA. As a result these two single cell organisms are fitted into different kingdoms.
ReplyDeleteBacteria and protist have many similarities and differences. One way they are different is that bacteria is considered a prokaryote which means it has no membrane or nucleus. A protist is considered a eukaryotic which means it has a nucleus and organelles. One way they are similar is that they both use flagella to move around.
ReplyDeleteEmily, I agree that bacteria are unicellular and they both belong to different kingdoms.
ReplyDeleteI agree with Victoria, as the way they are different are that bacteria is considered prokaryote and protist is considered eukaryotic. Similarities are that they both have flagellum.
ReplyDeleteBacteria, seems more variable in types and effects of. Bacteria can both harm and save people. Protists are more everyday, as well as less dangerous. Bacteria fuels off carbohydrates similar to Protists but bacteria are much smaller.
ReplyDeleteYeah, Max makes a good point in that bacterial cell structure is more basic than one of a protist which is not just bigger but has more moving parts than bacteria
ReplyDeleteBacteria and protist are both single celled. Both bacteria and protists are both have ribosomes. They also both have cell walls. They are different because they both have different cell structures. They are also different because protists are eukaryotic and bacteria is not. They are also in different kingdoms. This is how they are similar and differences.
ReplyDeleteI agree with victoria because she also mentioned the prokaryotic and the eukarotic aspect of why they are different. We also both have similar similarities about why they are the same.
ReplyDeleteBacteria and protists are both single celled organisms. Bacteria and Protists both have ribosomes and they also have a cell wall. But they are indeed different in a way because they have two different cell structures. Additionally, they are different because protists are just eukaryotics and bacteria is considered a prokaryotic. Protist are more a daily thing is not as dangerous and bacteria is much more smaller.
ReplyDeleteBacteria and protists can both use flagellum to move around. Bacteria and protists both can be in moist surroundings. Protists have a nucleus while bacteria do not. Bacteria can be found everywhere while protists can only be found in moist places. Bacteria are only unicellular but protists can be multicellular. Bacteria are much smaller than protists.
ReplyDeleteI agree with Jason that protists are a bit more everyday and that they're less dangerous. Also bacteria are much smaller than protists.
ReplyDeleteThere are many similarities and differences between protists and bacteria. They are different because a protist is eukaryotic which means it has a nucleus and has a membrane. Bacteria is prokaryotic which means it does not have a nucleus and does not have organelles. Another difference is that they fall under two different kingdoms, protists fall under the kingdom protista and bacteria fall under the kingdom bacteria. One similarity between bacteria and protists is that they are both singled celled organisms.
ReplyDeletewait that last post was actually Alexi (me) not Jacob.....
ReplyDeleteThere are similarities between protists and bacteria, such as the fact that they are single-celled organisms, but there are also many differences. A difference difference between them is that protists are eukaryotic (which means that they have a nucleus and a membrane) and bacteria is prokaryotic (which means that it doesn't have a nucleus and other organelles). Other differences they have, put them in two different kingdoms.
ReplyDeleteBacteria and protists are similar because they are both single cell organisms and they are microscopic. They differ because bacteria are much older than protists. Another big difference between bacteria and protists is that bacteria is prokaryotic and protists are eukaryotic.
ReplyDeleteJay makes a good point about the structures of the organisms and how they are similar or different to one another
ReplyDeleteI like Emily's comment about the different kingdoms. I kind of forgot about the different kingdoms myself and that's a really important difference between them.
ReplyDeleteIf you were to glance at at a protist and bacteria it would be hard to spot the differences right away. The are both microscopic, both can be single celled and both can use flagella and they both can have cilia. The main differences are that bacteria are prokaryotic (no nucleus) and protists are eukaryotic(having a nucleus. They are in different kingdoms as well.
ReplyDeleteComment-
ReplyDeleteEmily-
I forgot about how bacteria can be good or bad and how protists are sort of neutral in their good and badness.
Bacteria and protist may seem similar but they also have significant differences. One major difference that they have is their structures. Bacteria is considered an organism. Bacteria reproduces asexually. Bacteria does not have a nuclear envelope. Protist, on the other hand, do have a nuclear envelope. Protist also have other organelles. Protist sexually reproduce. They also have a cytoskeleton. One major similarity is the fact that they are both single celled.
ReplyDeleteProtists and Bacteria are very different from each other. Bacteria are organisms without a membrane or nuclear envelope, and protists are eukaryotic and do have a membrane organelles, and a nuclear envelope. Bacteria also reproduce asexually and protists reproduce either sexually or go through mitosis. Although the differences are vast, they are both single-celled.

I completely forgot about the difference between the ages of the two organisms. GOOD POINT.
John, I like your input! You seem to know many specific details of bacteria and protists. In what kingdoms are bacteria in, and what kingdoms are protists in?
ReplyDeleteOne difference about bacteria and protists is that they are in different kingdoms. Another difference is that bacteria are prokaryotic and protists are eukaryotic. They also reproduce differently. A similarity between them is that they are both single celled organisms making them very simple.

Protists and bacteria are very different Protists are eukaryotes and bacteria are prokaryotes. They are both also in different kingdoms. Another major difference is the way they reproduce, Protists reproduce asexually and bacteria produce sexually.
ReplyDeleteProtists and bacteria have similarities and differences. One similarity is they both are single celled. However Protists are eukaryotic and bacteria is prokaryotic. Both organisms both help the world in some kind of way.

Good point Jason. But protists feed off the sun and you never said that and it seems relevant. Otherwise good point!

ReplyDeleteI like what your said about protists and bacteria being different because of their ways of reproduction. good job!
Commenting on Catherine-
ReplyDeleteI think you have a strong point about bacteria are prokaryotic and protists are eukaryotic. This is a really good difference between the two!
Bacteria and protist have things alike and different from eachother. Both bacteria and protist are single celled organisms. Bacteria are prokaryotic while protists are eukaryotic. There is no way that just by looking at them you could tell the difference, this is because they are both very small the human eye itself can not see them with out a microscope. Bacteria reproduces asexually and do not have a nuclear envelope and protists do have an nuclear envelope.

ReplyDeleteAmanda
I think that you mention a good point when you said that protists are eukaryotic, and then explained what that meant. and how you said that bacteria was prokaryotic and also explained what that meant.
Protists are a form of eukaryotic bacteria, meaning they have a nucleus. Bacteria are mainly prokaryotic who don't have a nucleus. But there are some similarities. Protists and bacteria both use flagella to move around and collect food. They both have a cell wall, ribosomes, and a cell membrane. Prokaryotes also do not have most organelles that eukaryotes do.
ReplyDeleteComment to Michael Aldoroty: good point, both of the them are both single celled organisms.
Comment to Alisha Kothari: Pointing out that they are in different kingdoms is a good observation, I personally didn't realize that.
Bacteria and protists are both single celled organisms. That is about as far as their similarities go. They are from completely different kingdoms. Bacteria are Prokaryotes, while protists are Eukaryotes. Eukaryotic cells are much more complicated than Prokaryotic cells. Eukaryotic cells have a nucleus and organelles. While Prokaryotic cells do not. So overall there are more differences between bacteria and protists than similarities.
ReplyDeleteComment:
ReplyDeleteresponding to pretty much everybody, I agree that both are single celled organisms and that they are from different kingdoms, people also found very interesting things that I had never known before.
Sami Lyons- I agree with yours completely. I did not know or I forgot that Eukaryotes have nucleus membranes and Prokaryotes do not.
ReplyDeleteEmily Ghazi- I really enjoyed your response. It really helped me understand the comparison between prokaryotes and eukaryotes. It is good to know that Protists and bacteria are both single celled, I forgot to write that in my post! Anyway, good job.
ReplyDeleteBacteria and Protists are both unicellular organisms. Bacteria are Prokaryotes while protists are Eukaryotes. The only things that Prokaryotes and Eukaryotes have in common are a DNA strand, a cell wall, ribosomes, and a cell membrane. Bacteria are simple while protists are more complex. Protists and bacteria can both use flagellum to move. Also protists have a nucleus bacteria do not.
ReplyDeleteComment to Sarah Podolsky's post:
ReplyDeleteI agree with most of your post except when you said "Bacteria and protists are both single celled organisms. That is about as far as their similarities go." I disagree with this because bacteria are prokaryotic cells and protists are eukaryotic cells and the 4 things prokaryotic and eukaryotic cells share are a DNA strand, a cell wall, ribosome, and a cell membrane. Based on this information bacteria and protists do not only share the fact that they are both single celled organisms.
Comment to Kaya's post:
ReplyDeleteI agree with everything in your post and that protists and bacteria are very different but do share similarities. Also I liked how you said how protists and bacteria reproduced because I didn't know that.
Bacteria and protists have some similarities, but have many differences. Bacteria is made up of prokaryotic cells, whereas protists are made of eukaryotic cells. Also, bacteria do not have a nucleus, whereas protists do.
ReplyDeleteComment to Emily's post:
Great point about protists and bacteria being in different kingdoms! your in comment is in depth and helpful, but bacteria are not always single celled.
Comment to Annabel's post:
I agree with your comment and it is a really good point that they do share certain organelles such as DNA strands, cell walls, ribosomes, and membranes.
Bacteria and protists are very similar but have a few differences. The main difference is that Bacteria is made up of prokaryotic cells and protists are made up of eukaryotic cells.
ReplyDeleteReply to Annabel:
ReplyDeleteThis is great detail. Bacteria and protists are very similar except protists are eukaryotes, making them more complex. This makes it very clear, thanks!
Bacteria and Protists are both single celled organisms. But Protists are Eukaryotes while Bacteria are Prokaryotes. Also Protists are more complicated than Bacteria. Bacteria has no organelles and no nucleus.
ReplyDeleteBacteria are prokaryotic and protists are eukaryotic. The similarities between prokaryotes and eukaryotes are that they have DNA strands, cell walls, ribosomes and cell membrane. Other than these features (and that they are both unicellular), bacteria and protists are very different. Bacteria have a nuclear membrane and no membrane-surrounded organelles, while protists have just the opposite features.
ReplyDeleteAlisha: It was very interesting to mention how protists and bacteria reproduce in different ways.
Michael: Nice comment about how both help the world- didn't think of that!
Lucy
ReplyDeleteI liked how you said that they are so microscopic, humans cannot see them!
Bacteria and protists are different in that bacteria cells are prokaryotic, while protists are eukariotic. Their main similarity is that they are both unicellular. They both are not very complex due to being unicellular, yet they are in different kingdoms.
ReplyDeleteBeth: I like how you made it obvious what features each organism have.
Annabel: I like how you said how the organisms move.
Both bacteria and protists are microscopic, have positive and negative aspects and they are both living. They are different in that bacteria are only unicellular and do not have a nucleus.
ReplyDeleteSami Lyons: thanks for mentioning that they fall in different kingdoms, i did not know that!
Tess: it makes sense that bacteria would be older but i did not think to add that... thanks!
Protists contain eukaryotes, which contain nuclei. There's a fun fact about it: the prefix "euka" means "well, new". Bacteria, on the other hand, don't carry the fun chloroplasts and nucleus that protists have. Protists may go through photosynthesis, but bacteria only has its flagella to be thankful for. Luckily, protists and bacteria have some similarities: such as their single-cellularity. Neither of them are animals, fungi or plants. Bacteria fall under Kingdom Monera, and protists fall under Kingdom Protista.
ReplyDeleteComment-
Sophie Hoffer-
Nicely said, I almost overlooked the part about them both having flagella.
Both protists and bacteria are single celled. The move by flagella. Bacteria has no nucleus whereas protists have nuclei. That gives bacteria the title of prokaryotic and protists, eukaryotic.
ReplyDeleteBacterial cells are prokaryotic whereas protists are eukaryotic. Prokaryotes also lack certain organelles that protists have, such as mitochondria and endoplasmic reticulum.
ReplyDeleteProtists are eukaryotic and therefore much more complex than bacteria, so they are quite interesting creatures to observe. However, bacteria reproduce exponentially faster and are thus easier to run tests and experiments on. Also, comparing them provides a perspective on the evolution and development of consumers, producers, and decomposers, from prokaryotes to multicellular organisms.
ReplyDeleteReply to Patrice:
ReplyDeleteActually, many bacteria can photosynthesize as well. It is theorized that the formation of plant like protists' chloroplasts (the organs of photosynthesis) were originally photosynthetic bacteria that were captured by the cell.
Reply to Michael Aldoroty:
Actually, multicellular protists do exist. An example is giant kelp.
The largest differences between protists and bacteria are their age and simplicity. Since protists are so much more complex, it will cause slower evolution, and bacteria, because of their simplicity, will evolve faster.
ReplyDeleteResponse to John Carhart:
ReplyDeleteYou have a good point about needing careful inspection to tell the differences, as we saw in class looking through the microscopes. Also, it is a good point about them being in different kingdoms.
Bacteria and protists are very similar but also very different. Bacteria are prokaryotic so they don't have a nucleus and protists are eukaryotic so they have a nucleus and other organelles. Bacteria are extremely simple therefore they can adapt to their environments easily where protists more complex therefore they can't adapt as quickly or as effectively. They are similar because both bacteria and protists are unicellular.
ReplyDeleteBeth:
ReplyDeleteIt was really interesting that you said that you think that protists and bacteria are extremely different because they don't have that much in common. I never really thought of it that way! Nice post!

ReplyDeleteSarah P:
ReplyDeleteGood point about bacteria and protists being from totally different kingdoms, I didn't know that! I think that because bacteria and protists are from different kingdoms then they are going to have different features and cell structures which make them even more different. Good post!
Bacteria and protists are two very different types of organisms. Bacteria are pro-karyotes having no nucleus, membrane, or organelles. One thing they do have that protists don't is a cell wall. Protists on the other hand are eukaryotes having nuclei, membranes, and organelles. This makes them more complex than the bacteria.
ReplyDeleteBacteria and protists are different. They are also the same in some ways. They are both simple organisms that can be found in the same places. That means it is hard to distinguish them apart. Protists are usually bigger is size, therefore we could see them in the microscope easier.
ReplyDeleteThis one is really Jacob (me).
ReplyDeleteTo Alexis comment in my name,
ReplyDeleteI agree with those facts. But can't some bacteria can be eukaryotic?
To Henry,
ReplyDeleteI thought your explanation was very clear. I found the difference very easily. Thank you for your thoughts.
Bacteria do not have a name and are mainly single cell organisms. They are relatively simple and do not have a nucleus. Protists are similar, but they do have a nucleus and more parts to them.
ReplyDeleteTo Amanda,
ReplyDeleteI agree with you. You clearly stated the difference and explained it so that everyone can understand.
To Theo,
ReplyDeleteYour explantion is clear and comprehensive. It is short and to the point. I agree with your ideas.
As many have said, bacteria and protests are single cell organisms. Protists are eukaryotic, which means they posses all of the eukaryotic traits that prokaryotes don't have (such as: belonging to the animal, fungi, protista or plant kingdoms, has a nucleus and cell wall). Protists are much larger then bacteria, and bacteria are eukaryotes. Something they have in common is cilia (or flagella), which helps the organisms move.
ReplyDeleteResponse to Sarah Wilentz:
You are 100% right in saying that protists and bacteria have many similarities. Some things that you didn't mention that they have in common are a cell membrane, flagella and DNA.
Bacteria and Protists are very different from each other but also the same in some ways. They are both organisms but protists are eukaryotic and bacteria are prokaryotic. They both look the same so it is hard to distinguish which is which sometimes. Protists are more complex then bacteria as well. Protists are usually unicellular but sometimes are multicellular. Bacteria are just unicellular. Those are some similarities and differences between protists and bacteria.
ReplyDeleteTo Jacob:
ReplyDeleteI think your explanation is very well worded and basically covers the main differences and similarities.
To Samantha T. Slavin:
ReplyDeleteYour understanding seems phenomenal to me. You made very good points and some 90% of the people who posted didn't even touch upon. Great job keep up the good work. :)
Bacteria and protists differ in many ways, protists being more complex organisms. Bacteria are prokaryotic, lacking a nucleus, cell membrane, and organelles such as the mitochondria, while protists are eukaryotic and have such features. Protists, as all eukaryotes are, are much larger than bacteria as well.
ReplyDeleteTo the person who I believe is Adam Kern but in fact may be a person with the name Akern, you're right on the points of bacteria's older age as an organism and their ability to evolve faster.
ReplyDeleteTo Jacob's comment, I wouldn't be so quick to say that protists and bacteria are found in the same places. However, your comment that protists are much more easily visible under a microscope is very astute.
ReplyDeleteAlso, I made an error when I said that bacteria lack cell membranes. Both kingdoms possess them.
Comment:
ReplyDeleteIzzy, I thought what you wrote about protists not being able to adapt as easily was quite interesting. I had not thought about the simplicity of the bacteria enabling it to adapt more easily.
Comment:
ReplyDeleteLucy S., your comment about the way that bacteria produce was intriguing. It is interesting to see the differences in the ways that the two organisms reproduce.
Although both bacteria and protists are single-celled organisms, they are very different. Bacteria are prokaryotes, they do not have a nucleus or a membrane bound DNA and lack organelles. Protists are eukaryotes, they have a nucleus and a membrane bound DNA but they do not have a cell wall. Because of these differences, they fall into different kingdoms.
ReplyDeleteTo Jacob: It is true that it is hard to distinguish bacteria and protists apart, but I do not believe they are necessarily found in same places.
ReplyDeleteBoth bacteria and protists can compare and contrast in many ways, being that they have some similarities as well as their differences. For example, bacteria are prokaryotes, meaning that they only have one cell and no nucleolus, while protists are eukaryote which have multiple cells. Additionally, protists also do not have a cell wall unlike bacteria and therefore they don't stay in specific shapes like bacteria and are constantly changing shape.
ReplyDeleteIzzy: I think that you got a really good understanding of what differentiates as well as what make bacteria and protists similar.
ReplyDeletePatrice: I enjoyed reading your response, as well as leaving more about the prefix "euka"!
Protists and Bacteria are quite different and yet quite similar. Protists are eukaryotic while bacteria is prokaryotic. While protists have all of the organelles and membrane bound nucleus and DNA, bacteria has a cell wall. While bacteria is only one cell, protists could have one or hundreds of cells.
ReplyDeleteHi Jacob. I thought that how you stated the size differentiation was good, and from what I read, you were the only one who mentioned it.
ReplyDeleteHi Beth. I liked how you gave a lot of detail about how the membranes were different: "nuclear".
ReplyDeleteProtists and bacteria very similar in the fact that they are both unicellular and both use flagellum to propel and move themselves. But they are diversely different because protists do not have a cell wall while bacteria often have one.
ReplyDeleteComment:
Cecely- I agree, they are a bunch of differences, including the fact protists do not have a cell wall as well as a nucleus.
Patrice: I didn't know about which kingdom each falls under. It's so interesting to learn about that kind of stuff.
Bacteria and protists are both single celled organism yet bacteria are prokaryotes and don't have membrane, a nucleus or a cell wall. Unlike protists that do have membrane, a nucleus, a cell wall and are eukaryotes. Both are in different kingdoms.
ReplyDeleteBacteria and protists are similar in that they are both single-celled organisms. However, they share little else in common. Bacteria are prokaryotes, meaning that have no nucleus and no organelles, but a cell wall. Protists are eukaryotes, meaning that they do have a nucleus, and are more complex than bacteria.
ReplyDeleteJacob- i agree with you that protists are bigger in size and are easier to see.
ReplyDeleteAnnabel- i like how you explained how both organisms move.

ReplyDeletePatrice:
I forgot about both photosynthesis and flagella. It's interesting how in fact similar they are, but yet so different. Since they are single-celled, they would seem to be precisely the same, but if you take a close look inside them, there are almost opposites. They are not even in the same kingdom.
Comment-
ReplyDeleteTaylor:
I like what you said about size...during our last lab, I realized that protists were tiny, so the fact that you bring up the point about bacteria is very interesting.
Bacteria are prokaryotes without organelles and its DNA is not within the nucleus. Protists are eukaryotic, meaning that the DNA is found in compact chromosomes within the cell. They are similar because they are both single-celled organisms and some organisms in both groups can photosynthesize.

That is very interesting that protists can have hundreds of cells.
Cecley:
I did not know that protists can change shape while bacteria cannot. It is a very interesting point you bring up about the cell wall affecting the shape of a cell.
Protists are eukaryotic. They have a nucleus, a membrane and organelles. Both protists and bacteria are single celled. Bacteria, on the other hand, are prokaryotic. They do not have a membrane or a nucleus, but they do have a cell wall. Both of them fall into different kingdoms because, in fact, they are different.
ReplyDeleteComment:
Helen, you just reminded me of the flagella. Thanks for that. You have a very sophisticated way of talking.
Nicki: I agree with what you have said. I like how your response is detailed and well written.
Xavier, I agree with mostly everything you said, they share important things in common but are so different. Both bacteria and protists are unicellular organisms meaning they are single-celled. They each have cell walls, a flagellum, and both can be harmful or useful. But as for these organisms difference, it mainly lies in the the levels of complexity in the organisms cell structure. Bacteria are prokaryotic. They don't have membranes or a nucleus. Protist are eukaryotes. They have membranes, a nucleus, and other organelles. That is why as Sophia mentioned they are in different Kingdoms, something I completely over-looked.
ReplyDeleteThe difference between bacteria and protists are that bacteria are prokaryotic and protists are eukaryotic. Also, they reproduce differently. Bacteria will reproduce asexually, while protists reproduce sexually. Protists are more advanced compared to bacteria, because they have organelles (them being eukaryotic) like their vacuoles.
ReplyDeleteReply to TCoop:
ReplyDeleteI completely agree with you that protists are much more complex compared to bacteria. Also, I agree that bacteria reproduce exponentially faster than protists. Good observation TCoop
There are many similarites and differences between bacteria and protists. For example both are single celled. But one major difference is that bacteria is a whole lot more complex. Also Bacteria is prokariotic and protists are eukariotic. In addition to all of that they both use flaggellum to move.
ReplyDeleteOne of the similarities between bacteria and protists are that they are both single cell organisms and they are both microscopic. They are different because protists are eukaryotic organisms and bacteria is prokaryotic organisms.
ReplyDeleteTo Tess,
ReplyDeleteI agree with your fact. But some bacteria can be eukaryotic. Your similarity was correct and it is a good point.
The bacteria and protist have many similarities and differences. One substantial similarity are, of course, that they are both organisms that have a single (1) cell. They both have DNA and have the ability to reproduce. Bacteria and Protists have cytoplasms and they both undergo the first stage of cellular respiration. Some differences that they both have is the fact that protists are eukaryotic which means that it has a nucleus and a mitochondria while bacteria is prokaryotic which does not have any of those. Not too long ago, bacteria were once considered protists until further review when proved that it was its own separate category.
ReplyDeleteComment:
ReplyDeleteXavier - I agree with mostly everything you say. Bacteria and Protists however have a little bit more in common that just the fact that they happen to both be single-celled organisms. But otherwise, your reasoning on the differences between the bacteria and protist make logical sense.
Bacteria are single celled prokaryotic organisms. They have no nucleus in them. Bacteria reproduce asexually. Protist are also single celled organisms. Protist are not prokaryotic they are eukaryotic and have a nucleus. Unlike bacteria protist reproduce sexually.
ReplyDeleteBacteria have neither a membrane-enclosed nucleus or membrane-enclosed organells making them prokaryotic. protists, also have one cell but are eukaryotic because they do have a membrane-enclosed nucleus. that makes protist a more complex organism.
ReplyDeleteJacob, i found your response to Tess's very interesting. at first I had not known that bacteria could be eukaryotic, but after further research i see that that might be true but from what i saw in my research is that they do not occur naturally
