Prokaryotic & Viruses


Prokaryotic Cells

  • They resembled the first living cells.
  • They are estimated to have formed within the first billion years of Earth.
  • Bacteriums are prokaryotic cells.
  • They have no nucleus or internal membranes, meaning their organelles un-bound by a membrane.
  • The cell membranes sometimes fold inwards to form a mesosome which will increase surface area.
  • They may have a photosynthesis lamella which can also increase surface area.
  • They are mostly unicellular.
