cell wall structure
Archaea differ from true bacteria mainly in their cell envelope chemistry — archaeal cell walls lack peptidoglycan and have unique membrane lipids (ether-linked isoprenoids), whereas eubacterial cell walls usually contain peptidoglycan. Both are prokaryotes (no nucleus) and show varied nutrition and body forms.
