• Prokaryotic cells do not have a nucleus or
  membrane bound organelles.
• These are the most simple types of living cells.
• Examples cyanobacteria, E.Coli,

  bound organelles.
• Plants, Animals, Fungus and Protists are all
  eukaryotes.

• Eukaryotes can be unicellular
• organisms made only of one cell
