    • what are some examples of prokaryotic cells?
      • bacteria
      • archaea
    • what are the major distinguishing features of prokaryotic cells?
      • they have no nucleus
      • they don’t have any internal membranes (no membrane-bound organelles)
    • what increases the membranes surface area in some prokaryotes?
      infolding of the cell membrane in a mesosome or photosynthetic lamellae
    • what do prokaryotes rarely form?
      they rarely form multicellular structures
    • what are prokaryotes often described as?
      unicellular
    • why are prokaryotes sometimes described as ‘acellular’?
      as their cells are not divided
    • what do all prokaryotes have?
      • DNA molecule loose in cytoplasm
      • peptidoglycan (murein) cell wall
      • 70S ribosomes
      • cytoplasm
      • cell membrane
    • what do some prokaryotes have?
      • slime coat
      • flagella (one, some or many)
      • photosynthetic lamellae holding photosynthetic pigments
      • mesosome - possible site of aerobic respiration
      • plasmids
