- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.
