Six-Kingdom
Classification
Classification
 Aristotle
first classified organisms as either
plants or animals…. This was good until…
 There are forms of life that do not fit into
those categories!!!
 Currently, we use the six-Kingdom
classification system..
 *** use to be 5, but we separated
Eubacteria and Archaebacteria…Why?
The Six Kingdoms

Archaebacteria
 Unicellular
prokaryotes.
 Do not have a nucleus
 Live in Harsh environments.

Eubacteria
 Unicellular
Prokaryotes
 Do not have a nucleus
 The bacteria around us
 Can be good and bad…how???
 Reproduce Binary Fission
Protista
 Most
are unicellular eukaryotic
 Can be heterotrophic or autotrophic
 This is the place to put all Eukaryotes that
are not plants, animals, or fungi.
 Not necessarily related, but unsure where
to place them
Fungi
 Multicellular
Eukaryotic
 Heterotrophic…decomposers
 Over 100,000 species of fungi
including fungi, mushrooms,
mildews, molds.
Plantae
 Multicellular
eukaryotic
 Autotrophic (can make their
own food…Photosythesis)
 Examples include mosses,
ferns, conifers, and flowering
plants.
Animalia

Multicellular Eukaryotic
Heterotrophic
Most animals have
symmetric body
organization and move
about in their environment
Examples: Birds, insects,
worms, mammals, reptiles,
and humans
