WebFor instance, the cell walls of all bacteria contain the chemical peptidoglycan. Archaeal cell walls do not contain this compound, though some species contain a similar one. Likewise, archaea do not produce walls of cellulose (as do plants) or chitin (as do fungi). The cell wall of archaeans is chemically distinct.
WebAlmost all prokaryotes have a cell wall, a protective structure that allows them to survive in extreme conditions, which is located outside of their plasma membrane. In contrast, some eukaryotes do have cell walls, while others do not. The composition of the cell wall differs significantly between the domains Bacteria and Archaea.
