Primary Subdivisions of Cellular Organisms -

Group	Cell structure	Properties	Constituent groups
Eukaryotes	Eukaryotic	Multicellular; extensive differentiation of cells and tissues. Unicellular, coenocytic or mycelial; little or no tissue differentiation	Plants (seed plants, ferns, mosses); Animals (vertebrates, invertebrates) Protists (algae, fungi, protozoa).
Eubacteria	Prokaryotic	Cell chemistry similar to eukaryotes.	Most bacteria.
Archaebacteria	Prokaryotic	Distinctive cell chemistry	Methanogens, halophiles, thermoacidophiles
