Bacillus | rod shaped |
coccus | spherical ex: ball |
spirella | spiral shaped ex: a cork |
vibrio | comma shaped |
prokaryote | "pre nucleus" |
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. |
