Tree of Life
Domains
• Domain Bacteria:
▫ Unicellular
▫ Prokayotic
▫ Thick, rigid cell walls surrounding a cell
membrane
▫ Cell walls contain peptidoglycan
▫ Correspond to Kingdom Eubacteria
▫ Can be autotrophic or heterotrophic
▫ Example: E. coli, Streptococcus

Unicellular
Prokaryotic
Cell wall surrounds a cell membrane
Cell wall does not contain peptidoglycan
Can be autotrophic or heterotrophic
Correspond to the Kingdom Archeabacteria
Example: halophiles, methanogens
Domains
• Domain Eukarya
▫ Contains all organisms that have a nucleus
(Eukaryotic)
▫ Can be autotrophic or heterotrophic
▫ Can be unicellular or multicellular
▫ Some have cell wall and some do not
▫ Corresponds to Kingdoms Protista, Fungi,
Plantae, and Animalia
Kingdoms
• Kingdom Protista:
▫ Mostly unicellular
▫ Some autotrophic, some
heterotrophic
▫ Some have chloroplasts
(algae)
▫ Example: amoeba,
paramecium, giant kelp
Kingdoms
• Kingdome Fungi:
▫
▫
▫
▫
Heterotrophic
Cell walls made of chitin
Some unicellular, some multicellular
Example: mushrooms, yeasts
Kingdoms
• Kingdom Plante
▫ Multicellular
▫ Autotrophic (photosynthetic)
▫ Nonmotile
▫ Cell walls of cellulose
▫ Have chloroplasts
▫ Example: mosses, ferns,
flowering plants
Kingdoms
• Kingdom Animalia:
▫
▫
▫
▫
Multicellular
Heterotrophic
No cell walls or chloroplasts
Example: sponges, worms, insects, fishes,
mammals
