Detailed explanation-1: -Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
Detailed explanation-2: -Archaebacteria have different cell membrane structures than other bacteria. The lipids in archaebacteria cell membranes are ether-linked compared to ester-linked in other bacteria. The difference in the cell membrane structure makes them more resistant to harsh environmental conditions.
Detailed explanation-3: -A possible answer is: Bacteria contain peptidoglycan in the cell wall; archaea do not. The cell membrane in bacteria is a lipid bilayer; in archaea, it can be a lipid bilayer or a monolayer. Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl.
