| morphology | shape |
| Archaea | prokaryotic, cell walls lack peptidoglycan, live in extreme environments: methanogens, extreme halophiles (high salt), extreme thermophiles (heat) |
| Bacteria | cell wall: carbohydrate and protein complex, reproduce binary fission (spilt) |
| Fungi | eukaryotes (contain membrane bound organelles) can be large and multicellular (mushrooms) can be unicellular- yeasts. Oval shaped, larger than bacteria, molds, can reproduce asexually and sexually. |
