The Six-Kingdoms

• Eubacteria• Archaebacteria• Protista• Fungi• Plantae• Animalia

Eubacteria and Archaebacteria(Monera)

• Prokaryotes– Lack a nucleus– Lack mitochondria and chloroplasts– Reproduce asexually

• First living organisms to evolve on theearth.

Eubacteria and Archaebacteria• Archaebacteria –

anaerobic bacteria– Thermophiles - Heat loving

bacteria.– Halophiles - Salt loving

bacteria– Acidophiles - bacteria

which thrive under highlyacidic conditions.

– Methanogens - methaneproducing bacteria

Eubacteria and Archaebacteria(Monera)

• Eubacteria – All other bacteria.

Esherischia coliSalmonella Cyanobacteria

(blue-green algae)

Protista• Single celled eukaryotic organisms.• Can have flagella• Can be autotrophic or heterotrophic.• Reproduction can be sexual or asexual

Amoeba Paramecium Plankton

4

Fungi• Heterotrophic• Eukaryotic• Cell walls made of

chitin.• Sexual and asexual

reproduction

Plantae• Multicellular• Eukaryotic• Photosynthetic• Cell walls made of cellulose.
