Which statement best describes prokaryotes?

• A. They are grouped into two domains: Bacteria and Archaea.
• B. They have a membrane-bound nucleus.
• C. They are all multicellular.
• D. They rely exclusively on photosynthesis.

Answer: (A)

Prokaryotes are organisms without a membrane-bound nucleus, and they are grouped into two major domains, Bacteria and Archaea. This labeling reflects how their cells organize genetic material and their evolutionary relationships, setting them apart from eukaryotes, which have a nucleus. Prokaryotes are typically unicellular, so the statement that they are all multicellular isn’t accurate. Their metabolism is diverse as well; some prokaryotes do photosynthesize, but many obtain energy in other ways, so they don’t rely exclusively on photosynthesis. Because of these points, grouping prokaryotes into the two domains Bacteria and Archaea best describes what they are.
