Which term describes single-celled organisms that are prokaryotes?

Explanation:
Single-celled prokaryotes are bacteria because they are cells that lack a true nucleus and membrane-bound organelles, existing as single, independent cells. Bacteria are the classic example of unicellular organisms with a simple cell structure. Viruses aren’t cells at all; they’re genetic material enclosed in a protein coat and require a host cell to reproduce. A Phase 2 Clinical Trial is a stage of medical research, not an organism. Mammalian cells are eukaryotic—meaning they have a nucleus and organelles—and are typically part of multicellular organisms, not prokaryotes.
