Difference in Cell structure. The general cell structure of archaea and bacteria are the same but composition and organization of some structures differ in archaea. Similar to bacteria archaea do not have interior membranes but both have 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.
