Archaea = similar to Eubacteria with a few differences. Now considered separate from Eubacteria. Includes Kingdom Archaebacteria
Bacteria = includes Kingdom Eubacteria
(Monera) or prokaryotes
3) Eukarya = includes several kingdoms (eukaryotes)

5. Kingdoms of eukaryotes
Plantae = multicellular, photosynthesis
Animalia = multicellular
Fungi = Most multicellular (mushrooms, molds, yeast)
Protista = most unicellular, come multi-cellular or colonial (amoeba, algae, kelp, slime mold)
See figures and in textbook for details and easy comparison of all domains and kingdoms
