1. The Six Kingdoms

2. 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

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

5. 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

6. 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

7. Archaebacteria
-”ancient bacteria” -existed before dinosaurs -live in extreme environments -hot springs -acidic environment -methane -unicellular prokaryotes -some autotrophs, some heterotrophs

8. Extreme Environments

9. Eubacteria
Chemical makeup is different from that of archaebacteria. -unicellular prokaryote -some autotrophs, some heterotrophs

10. A Typical Bacteria Cell

12. Protists
-“odds and ends” kingdom because its organisms are pretty different from one another
-most unicellular, some multicellular
-eukaryotes
-some autotrophs, some heterotrophs

13. Protozoa

14. A Ttypical Protist

15. Fungi -mushrooms, mold, and mildew
-most are multicellular, some (like yeast) are unicellular
-eukaryotes
-all are heterotrophs
-eat dead or decaying organisms

16. FUNGI

17. FUNGI includes: Unicellular Yeast

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

19. Plants -all plants are multicellular -all are eukaryotes
-plants are autotrophs

20. Typical Animal Cell

21. Animals -all are multicellular -all are eukaryotes
-all are heterotrophs

22. Typical Animal Cell

23. 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)
