Viruses - electron microscopy images – viruses are tiny! - variety of morphology

cyanobacteria proteobacteria

Prokaryotes: Eubacteria - proteobacteria and cyanobacteria are believed to be precursors to mitochondria and chloroplasts in eukaryotes

Vibrio cholerae Borrelia burgdorferi

- responsible for causing many diseases in humans, but some are beneficial

extreme thermophiles methanogens

Prokaryotes: Archaea - differ from eubacteria in cell membrane and cell wall chemical makeup

psychrophiles halophiles

- inhabit extreme environments

Protists - wide variety of morphology, feeding modes, and reproduction strategies - e.g. amoebas, red algae, diatoms, slime moulds
