Prokaryotic cells do not have a nucleus, while eukaryotic cells do have a nucleus. Eukaryotic cells can occur as single-celled or multi-celled organisms, while prokaryotic cells are generally single-celled. Both eukaryotic and prokaryotic cells have cell membranes. Therefore, option B is the correct choice. Option A is incorrect because prokaryotic cells are generally single-celled and eukaryotic cells may occur as single or multi-celled. Option C is incorrect because eukaryotic cells make up both single-celled and multi-celled organisms; it is not restricted to multi-cellular organisms. Option D is incorrect because the earliest prokaryotic cells appeared about 3.5 billion years ago while the earliest eukaryotic cells appeared about 1.2 billion years ago.
