The Six Kingdoms

The Six Kingdoms. 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.

  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 broadesttaxon: KPCOFGS

  3. 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

  4. 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

  5. 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

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

  7. Extreme Environments

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

  9. A Typical Bacteria Cell

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

  11. Protozoa

  12. A Ttypical Protist

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

  14. FUNGI

  15. FUNGI includes:Unicellular Yeast

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

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

  18. Typical Animal Cell

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

  20. Typical Animal Cell

  21. 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)
