Bacteria are prokaryotic cells that contain cytoplasm enclosed within a cell membrane and usually a cell wall. Viruses are acellular entities; they consist of genetic material (DNA or RNA) enclosed in a protein coat (capsid) and sometimes an outer envelope, but they do not have cytoplasm or cellular organelles like mitochondria.

– Bacteria are living, single-celled organisms (prokaryotes).
– Viruses are non-living particles that require a host cell to reproduce.
– Prokaryotes (like bacteria) have cytoplasm but lack membrane-bound organelles like mitochondria.
– Viruses lack cellular structure, including cytoplasm, cell membrane, and organelles.

Option B is incorrect because bacteria do not have mitochondria (membrane-bound organelles). Option C is incorrect because neither viruses nor bacteria have mitochondria. Option D is incorrect because bacteria have a cell membrane, while viruses do not have a cell membrane in the cellular sense (though some have an envelope derived from host cell membrane).
