Domain Archae
Kingdom Archaebacteria
Prokaryotic – does not have a nucleus
 Unicellular – single cell organism
 Some autotrophic, some heterotrophic
 Reproduce asexually (binary fission)

Domain Archae
Kingdom Archaebacteria

Some live in extreme environments
 High salinity
 Low oxygen concentrations
 High temperatures
 High or low pH
 Stomachs of grazing herbivores

Many live in oceans
Domain Bacteria
Kingdom Eubacteria
Prokaryotic – lack a nucleus
 Unicellular – single cell organism
 Some autotrophic, some heterotrophic
 Reproduce asexually (binary fission)

Domain Bacteria
Kingdom Eubacteria
Used in the production of food, oil spill
cleanup, and sewage treatment plants
 Decomposers – break down dead
organisms
 Some cause disease – strep throat, food
poisoning, etc.

Domain Eukarya
Kingdom Protista
Eukaryotic - have a nucleus
 Most unicellular, some multicellular
 Some autotrophic, some heterotrophic
 Reproduction can be asexual or sexual

Domain Eukarya
Kingdom Protista
Most diverse of the kingdoms
 Some people classify protists as any
eukaryote that is not a fungus, plant, or
animal
 Includes amoeba, paramecium, algae,
diatoms, and many more

Domain Eukarya
Kingdom Fungi
Eukaryotic - have a nucleus
 Some unicellular, most multicellular
 Heterotrophic
 Reproduction can be sexual or asexual

Domain Eukarya
Kingdom Fungi
Digest food outside their bodies and
then absorb it
 Many are decomposers
 Includes mold, mushrooms, and yeast

Domain Eukarya
Kingdom Plantae
Eukaryotic - have a nucleus
 Multicellular
 Almost all are autotrophic (some parasitic)
 Reproduction can be asexual or sexual

Domain Eukarya
Kingdom Plantae
Most need sunlight, water, minerals, and gas
exchange to survive
 Includes trees, grasses, mosses, ferns,
cactus, corn, ivy, flowers, etc.

Domain Eukarya
Kingdom Animalia
Eukaryotic - have a nucleus
 Multicellular
 Heterotrophic
 Most reproduce sexually but some asexual

Domain Eukarya
Kingdom Animalia

Animals include lizards, grasshoppers,
spiders, sponge, dogs, humans, worms,
clams, fish, etc.
