The outer layer that covers all prokaryotes is the cell wall, which provides structural support and protection. In bacteria, this cell wall is primarily composed of peptidoglycan, while archaea have cell walls made of different materials, such as pseudopeptidoglycan or other polymers. Additionally, some prokaryotes may have an outer membrane or a capsule that further contributes to their protection and interaction with the environment.
