  • 1. Grade 9 Science Kingdoms of Life
  • 2. Classification of Living Things Living things can be sorted into these 5 kingdoms…but it’s not the only way! Kingdom Moneran (Bacteria) Kingdom Protista Kingdom Fungi Kingdom Plantae Kingdom Animalia
  • 3. Kingdom Moneran - Bacteria
    • microscopic, single-celled organisms
    • do not have a nucleus but do have a ring of DNA (prokaryotic)
    • do have a cell wall
    • Some can photosynthesize (autotrophic)
    • Most are heterotrophic
  • 4. Bacteria
    • Some bacteria are useful – Lactobacillus bulgaricus used to make yogurt
    • Some bacteria are pathogens and cause disease, like Pneumococcus that causes pneumonia
  • 5. Kingdom Protista
    • single-celled organisms with a nucleus (eukaryotic)
    • All live in water
    • Includes a huge variety of organisms from giant kelp to amoeba
    • All have the same cell structure
    • Some can photosynthesize, others can’t
  • 6. Kingdom Protista
    • Chlorella
    • Plasmodium
    • Kelp
    • Algae
  • 7. Kingdom Fungi
    • Eukaryotic cells
    • Cannot photosynthesize
    • Heterotrophic
    • Have cell walls
    • Some single celled like yeast
    • Most multicellular (molds, mushrooms)
  • 8. Kingdom Fungi
  • 9. Kingdom Plantae
    • Multicellular – made up of lots of cells
    • Make their own food by photosynthesis (autotrophic)
    • Have cell walls
    • Lots of examples: flowering plants / non-flowering plants
  • 10. Kingdom Plantae
    • Mosses
    • Ferns
    • Flowering plants
    • Non-flowering plants
  • 11. Kingdom Animalia
    • Multicellular – made up of may specialised cells
    • heterotrophic
    • Can be further classified into vertebrates and non-vertebrates then into classes such as amphibians, reptiles, birds, mammals, insects
  • 12. Animals you may not have seen…
    • Aye-aye lemur
    • Star-nosed mole
    • Blob fish
    • Alligator snapping turtle
    • 3-toed Sloth
    • Preying mantis
    • Nudibranch
    • Some type of jellyfish!
  • 13. Limitations
      • Much more DNA evidence now
      • Three Domain System is more recent
  • 14. Another way of organizing…
  • 15. Lichens
    • formed by a fungus and cyanobacteria living symbiotically
    • * first to enter an uninhabited area, slowly break down rock
    • -
    • *they are indicator species: they are very sensitive to environmental change, don't tolerate chemical pollution, eg. sulphur dioxide
    • Don’t fit into ANY Kingdom!
  • 16. What about Viruses?
    • Are they living or not??
    • No one can decide!!
