  • Features of a prokaryote
    • Genetic material (DNA) - Nucleoid genophere
      • Circular loop of DNA, not associated with protein
      • Carried genetic info-for proteins
    • Cell wall
      • Made of peptidoglycan
      • Prevents osmotic lysis, right & strengthening
    • Capsule
      • Extra layer outside cell wall
      • Prevents from desccication (drying out) and some pathogens
    • Cytoplasm
      • Solution where many dissolved molecules are
      • Site of many metabloc reactions
    • Cell surface membrane (plasma membrane)
      • Phospholipid bilayer with proteins
    • Plasmids
      • Small loops of DNA, can replicate independently
      • Eg- Can pass on genetic info via conjugation to other species
  • Cell surface membrane (plasma membrane)
    • Phospholipid bilayer with proteins
  • Selectively permeable
    • Plasmids
      • Small loops of DNA, can replicate independently
      • Eg- Can pass on genetic info via conjugation to other species
    • Simple flagella (often present and may be more than one)
      • Thin rotating fibre
      • Responsible for movement of cell
