I Need Some Questions Answered About Bacteria For A School Project...?

i need these 2 questions answered...


9.Do they contain animal and plant like species?


10.Are they aerobic or anaerobic?

I Need Some Questions Answered About Bacteria For A School Project...?
As one other person pointed out, some bacteria use photosynthesis to get their energy, and so can be said to be like plants. As for animals? No. Really not. If your teacher says they are, take it from me, they're wrong.





They can be both areobic (uses oxygen for respiration) and anaerobic. Bacteria in your gut are anaerobic, other examples include Clostridium perfringens and Clostridium botulinum (causes botulism). Aerobic examples include Staphylococcus aureus and Streptococcus pneumoniae.





Oh, and many bacteria are what we call facultative anaerobes/aerobes, meaning they are not too fussy.
Reply:mmm, I think that are are like animal like species, the only thing is bacteria cells don't have a nucelus? I think they are in their own category. Because I'm not sure if they fall in Prokayotic or eukayotic cells. spell?





mmm and for the other question, I think anaerobic, bc isn't yeast kind of like bacteria? they don't require oxygen to produce, which is how they make alcohol, they grow faster.





well, everything was from memory, I might be wrong.
Reply:Bacteria called cyanobacteria are definitely plant-like because they contain chlorophyll and carry on photosynthesis.





Most bacteria are heterotrophs, so they are like animas.





Some bacteria are aerobic and others are anaerobic.
Reply:9. Offhand, I would say no, but I'm not sure what is meant by "animal and plant-like species." Bacteria are single cell organisms, whereas plants and animals are multicellular. Are you asking if there are bacteria that act like plants or animals using some large stretch of the imagination?





10. There are species of both aerobic bacteria (bacteria that live in the presence of oxygen) and anerobic bacteria (bacteria that only live in the absence of oxygen. Is there a specific species of bacteria that you're asking about? For example, Escherichia coli is an aerobic species and Clostridium difficile is an anaerobic species.
