Question

which of the following would allow you to confirm that the v. cholerae cell was a prokaryote and not a eukaryote?
presence of a cytoskeleton
presence of ribosomes
presence of a flagellum
absence of a nucleus
absence of any organelles

Explanation:

Prokaryotic cells lack a true nucleus, while eukaryotic cells have a membrane - bound nucleus. Both prokaryotes and eukaryotes can have a cytoskeleton, ribosomes, and flagella. Prokaryotes have some organelles like ribosomes, so the absence of any organelles is incorrect. The key differentiator here is the absence of a nucleus.

Answer:

absence of a nucleus
