The 6 Kingdoms

• Archaebacteria
• Eubacteria
• Protists
• Fungi

9
Archaebacteria

• Unicellular
• Prokaryotic no organized nucleus
• Autotrophs or heterotrophs
• Thermoacidophilethrives in strongly acidic
  environments at high temperatures
• Extreme halophiles
• Thrives in salty environments.

Ancient or Old Bacteria
10
Eubacteria New Bacteria

• Unicellular
• Prokaryotic
• Autotrophs or heterotrophs
• Ex. Staphylococcus and E-coli.

11
Protists odds and ends

• Unicellular or multicellular
• Autotrophs or heterotrophs
• Eukaryotic organized nucleus
• Ex. Amoeba, paramecium, slime molds, euglena,
  algae.

12
Fungi

• Most are multicellular
• Some are unicellular
• Eukaryotes
• Heterotrophs
• Feed on dead and decaying organisms
• Sessile-cannot move on own.
• Ex. Mushrooms, molds, mildew, yeast.

13
Plant

• Multicellular
• Eukaryotes
• Autotrophs
• Sessile
• Ex. Roses, magnolias.

14
Animals

• Multicellular
• Eukaryotes
• Heterotrophs
• Motile-can move on own
• Specialized sense organs
