List of the Three Domains and
the Six Kingdoms

1. Domain Bacteria

Kingdom Eubacteria

2. Domain Archaea

Kingdom Archaebacteria

3. Domain Eukarya

Kingdom Protista

Kingdom Fungi

Kingdom Plantae

Kingdom Animalia

Kingdom Eubacteria

Bacteria can live in many places on earth, inhabiting a wide variety of habitats, including other organismsUnicellularProkaryoticAutotrophic or heterotrophicThick cells walls with peptidoglycan

Kingdom Eubacteria

Bacteria come in different shapes, such as round, spiral and rod-shaped.

Kingdom Eubacteria

Bacteria can cause a wide variety of diseases, such as strep throat, food poisoning and the Black Death (bubonic plague of the Middle Ages)

Kingdom Eubacteria

Bacteria also play an important role in decomposition, nitrogen fixation and human digestion (E. coli)

Soybean root containing billions of bacteria

Kingdom Eubacteria

Procholorococcus an autotrophic bacterium What does that mean about how it gets its nutrients?

Kingdom Eubacteria

Bacteria from an Nitrifying Trickle Filter (NTF) stained with acridene orange. The stain makes
DNA appear yellow and
RNA appear orange.

Kingdom Archaebacteria

Bacteria that live in extreme habitats, such as hot springs, geysers, volcanic hot pools, brine pools, black smokersUnicellularProkaryoticAutotrophic or heterotrophicCell walls without peptidoglycan

Kingdom Archaebacteria

Morning Glory Pool in Yellowstone National Park note the bright colors from the archaebacteria growing in the extremely hot water.

Kingdom Archaebacteria

Some like it hot! Bacillus infernus

Kingdom Archaebacteria

Archaebacteria can live deep in the ocean near geothermal vents called black smokersThere is no light, so they carry out chemosynthesis instead of photosynthesis

Kingdom Protista

Extremely diverse groupEukaryoticMost unicellular, some colonial, some multicellularAutotrophic and heterotrophicSome with cell walls containing cellulose; some carry out photosynthesis with chloroplasts

Kingdom Protista

Volvox a colonial protist

Euglena - autotrophic

A slime mold

Amoeba - heterotrophic

Kingdom Fungi

EukaryoticMost are multicellularHeterotrophic (decomposers)Cell walls made of chitin

Kingdom Fungi

Stilton cheese

Bread mold

Kingdom Plantae

EukaryoticMulticellularAutotrophicCell wall of cellulose; chloroplasts present

Kingdom Plantae

Kingdom Animalia

EukaryoticMulticellularHeterotrophicNo cell walls, no chloroplasts

Kingdom Animalia

Coral snake

Sponge

Flatworm

Octopus

Jellyfish

Bear
