apart from their habits , bacteria and archea differ in cell wall structure and membrane lipid composition . A ll bacteria have peptidoglycans in the cells wall where as the archea do not . both also are different in the RNA polymerases and thus in their protein synthesis .I hope that can help you !!:))
Archaea differ from bacteria primarily in their cell wall composition and membrane lipid structure. Bacteria have peptidoglycan in their cell walls, while archaea do not; they may have pseudopeptidoglycan or other materials instead. Additionally, archaea have ether-linked lipids in their membranes, while bacteria have ester-linked fatty acids.
