Verified step by step guidance

Understand the structure of cell membranes in different domains of life: Eukaryotes, Archaea, and Bacteria.

Recall that eukaryotic cell membranes typically consist of a phospholipid bilayer with embedded proteins and may contain sterols like cholesterol for fluidity regulation.

Recognize that archaeal cell membranes are unique due to their ether linkages and can form either bilayers or monolayers, which is an adaptation to extreme environments.

Note that bacterial cell membranes generally consist of a phospholipid bilayer without cholesterol, which differentiates them from eukaryotic membranes.

Evaluate the statements based on the above knowledge: The statement about archaeal cell membranes forming bilayers or monolayers depending on environmental conditions is true, as it reflects their adaptive nature.
