E) multicellular

Question

Quizplus · Accepted Answer

Domain Bacteria consists of prokaryotic cells that have ester linkages in their phospholipids, distinguishing them from Domain Archaea, which have ether linkages. Option A is partially correct, but it also includes a characteristic that is specific to Domain Archaea. Option B is incorrect because complex cellular structures are generally associated with eukaryotic cells. Option C is incorrect because it incorrectly identifies Domain Bacteria as eukaryotic, and also describes a characteristic that is common to all cells, not specific to Domain Bacteria. Option E is also incorrect because bacteria are generally unicellular, although some may form colonies or biofilms.
