Which of the following BEST describes a bacterium?

Question

BlackTom AI · Accepted Answer

Question restatement: Which of the following BEST describes a bacterium?

Option 1: 'A virus that is transmitted by arthropods.' This is inaccurate because bacteria are not viruses; viruses are non-cellular parasites that require a host to replicate, whereas bacteria are cellular organisms. The mention of arthropods as transmitters is more characteristic of certain viral or parasitic pathogens, not a general description of bacteria.

Option 2: 'A eukaryotic cell' Incorrect because bacteria belong to the prokaryotes. Prokaryotic cells lack a true nucleus and membrane-bound organelles, which distinguishes them from eukaryotic cells.

Option 3: 'A prokaryotic cell' Correct because bacteria are single-celled organisms classified as prokaryotes. They typically lack a nucleus, have no membrane-bound organelles, and often have a cell wall made of peptidoglycan.

Option 4: 'A parasitic worm' Incorrect since parasites like worms are multicellular eukaryotes, not bacteria. This description would apply to organisms such as nematodes or cestodes, not to bacteria.
