There are six kingdoms of life that classify organisms based on cell structure, nutrition, and other factors. The kingdoms are Archaebacteria, Eubacteria, Protists, Fungi, Plants, and Animals. Archaebacteria and Eubacteria are prokaryotic organisms, while Protists, Fungi, Plants, and Animals are eukaryotic. The kingdoms differ in whether organisms are unicellular or multicellular, autotrophic or heterotrophic, and in other distinctive characteristics. These six kingdoms provide the broadest classification for organizing life on Earth.

The Six Kingdom of Classifiction

4. The History of Classification
• In the 1700’s, Linnaeus separated all life into 2
Kingdoms: Plants and Animals.
• More kingdoms added as knowledge of the diversity
of organisms increased.
• We currently have 6 Kingdoms.
• Remember: Kingdoms are the broadest taxon:
KPCOFGS

6. Six Kingdoms in Taxonomy
organized according to type of cells,
ability to make food, number of cells in
body
1. Archaebacteria
2. Eubacteria
3. Protists
4. Fungi
5. Plants
6. Animals

7. Terminology
Getting food
autotrophs – make own food
hetertrophs – get food from other sources
Type of cells
prokaryotic – no nucleus, membrane bound
organelles, DNA is circular (plasmid), do contain
ribosomes, smaller
eukaryotic – with a nucleus and organelles, DNA in
chromosomes, larger

8. Terminology Continued
Body type
unicellular – made of only one cell
multicellular – made of more than one cell;
-have cells with special functions
Reproduction
sexual – need male and female parents
asexual – need only one parent

9. Kingdom Archaebacteria
Go to
Section:
Cell Type Prokaryote
Number of Cells Unicellular
Nutrition Autotroph or Heterotroph
Location Extreme Environments Volcanoes,
Deep Sea Vents, Yellowstone Hot
Springs
Examples Methanogens
Thermophiles
-”ancient bacteria”
-existed before dinosaurs

10. Extreme Environments

11. Kingdom Eubacteria
Go to
Section:
E. coli
Streptococcus
Cell Type Prokaryote
Number of Cells Unicellular
Nutrition Autotroph or
Heterotroph
Examples Streptococcus,
Escherichia coli
(E. coli)
Chemical makeup is different from
that of archaebacteria.

12. A Typical Bacteria Cell

14. Kingdom Protista
Go to
Section:
Paramecium
Green algae
Amoeba
Cell Type Eukaryote
Number of Cells Most Unicellular,
some multicellular
Nutrition Autotroph or
Heterotroph
Examples Amoeba,
Paramecium,
Euglena,
-“odds and ends” kingdom because its
organisms are pretty different from one
another

15. Protozoa

16. A Typical Protist

17. Kingdom Fungi
Go to
Section:
Mildew on Leaf
Mushroom
Cell Type Eukaryote
Number of Cells Most multicelluar,
some unicelluar
Nutrition Heterotroph
Example Mushroom, yeast,
mildew, mold
Most Fungi are
DECOMPOSERS

18. FUNGI

19. FUNGI includes:
Unicellular Yeast

20. A Typical Fungal Cell
Fungal Cells HAVE CELL
WALLS !!!!

21. Kingdom Plantae
Go to
Section:
Ferns :
seedless
vascular
Sunflowers:
seeds in
flowers
Douglas fir:
seeds in cones
Mosses growing
on trees
Cell Type Eukaryote
Number of Cells Multicellular
Nutrition Autotroph
Examples Mosses, ferns,
conifers,
flowering plants

22. Typical Plant Cell

23. Kingdom Animalia
Go to
Section:
Sage grouse
Poison dart frog
Bumble bee
Sponge
Jellyfish
Hydra
Cell Type Eukaryote
Number of Cells Multicellular
Nutrition Heterotroph
Examples Sponges,
worms, insects,
fish, mammals

24. Typical Animal Cell

25. The Six Kingdoms Review
• Eubacteria- “true” bacteria (prokaryotic)
• Archaebacteria – “ancient” bacteria (prokaryotic”
• Protista – WEIRD organisms!!!! (eukaryotic)
• Fungi – digest dead or decaying matter (eukaryotic)
• Plantae - stationary, photosynthetic (eukaryotic)
• Animalia – mobile heterotrophs (eukaryotic)
