Verified step by step guidance

Understand the structure of cell membranes: Cell membranes are primarily composed of lipids, and the type of lipids can vary among different domains of life.

Identify the unique lipid composition in Archaea: Archaea have cell membranes composed of glycerol-ether lipids, which are distinct from the glycerol-ester lipids found in Bacteria and Eukaryotes.

Recognize the biosynthesis process: These glycerol-ether lipids in Archaea are biosynthesized from isoprene units, which is a key differentiator from other domains.

Compare with other domains: Bacteria and Eukaryotes typically have glycerol-ester lipids, not glycerol-ether lipids, in their cell membranes.

Conclude the characteristic feature: The presence of glycerol-ether lipids biosynthesized from isoprene units is a characteristic feature of Archaea, distinguishing them from Bacteria, Eukaryotes, and Protists.
