    • Archaeal membranes
      • Isoprenes instead of fatty acids
      • Ether linkages in phospholipid
      • Lipid monolayers not biolayers
    • Cell structure
      • Glycocalyx
      • Cytoplasmic membrane
      • Ribosomes
      • Cell wall
      • Nucleoid
    • Uptake of nutrients
      • Endocytosis (eukarya only)
      • Passive diffusion (all)
      • Group translocation (not eukarya)
      • Facilitated diffusion (all)
      • Active transport (all)
    • Bacterial cell envelope
      • Can act as an endotoxin
      • Stabilizes outer membrane structure
      • Protection from host defenses
      • S layers
    • External structures
      • Archaeal flagella are thinner
      • Flagella for movement
