Archaea & Bacteria

What is the main difference between prokaryotes and eukaryotes?

• Prokaryotes have a nucleus, while eukaryotes do not.

• Prokaryotes do not have a nucleus or membrane-bound organelles, while eukaryotes do.

• Prokaryotes are larger than eukaryotes.

• Eukaryotes reproduce asexually, while prokaryotes reproduce sexually.

What are archaea?

• A group of single-celled microorganisms that are prokaryotes, meaning they do not have a nucleus or other membrane-bound organelles.

• A type of multicellular organism that has a complex cellular structure with a nucleus.

• A category of viruses that infect bacteria and other microorganisms.

• A group of eukaryotic organisms that are primarily found in extreme environments.

What is the role of bacteria in the environment?

• Bacteria are primarily responsible for photosynthesis.

• Bacteria play essential roles in nutrient cycling, decomposition, and some are involved in nitrogen fixation.

• Bacteria are harmful organisms that cause diseases only.

• Bacteria are only found in soil and have no significant role in the environment.

What are bacteria?

• Single-celled microorganisms that are also prokaryotes, found in various environments.
