  1. 6 Kingdoms Unit 2 - Biodiversity

  2. It’s Alive! • What qualities distinguish something as “living”? • It can…. • Grow and develop • Reproduce • Obtain and use materials and energy • Respond to their environment • Change over time • Are based on a universal genetic code • Are made up of units called cells

  3. How are these living things organized? • Kingdom • Phylum • Class • Order • Family • Genus • Species

  4. How are organisms classified at the Kingdom Level? • Number of cells • Unicellular or Multicellular • Mode of Nutrition • Autotrophic or Heterotrophic • Type of cells • Prokaryotic or Eukaryotic • Cell wall structure • Are they there? • If they are what are they made of?

  5. Number of Cells Unicellular Multicellular • Made up of one cell • Made up of 2 or more cells.

  6. Mode of Nutrition Autotrophic Heterotrophic • Make their own food/energy • Get energy from other organisms

  7. Cell Type Prokaryotic (BACTERIA ONLY!!) Eukaryotic • No nucleus or membrane bound organelles • Has a nucleus and membrane bound organelles

  8. Cell Walls Some have cell walls with… Some don’t have cell walls… • Peptidoglycan (some bacteria) • Cellulose (plants, some protist) • Chitin (fungi) • All Animals • Some protist

  9. Kingdom Archabacteria • Prokaryotic • Unicellular • Cell walls without Peptidoglycan • Some autotrophic, some heterotrohpic • Found in harsh, extreme environments

  10. Kingdom Eubacteria • Prokaryotic • Unicellular • Cell walls with Peptidoglycan • Some autotrophic, some heterotrohpic • Found everywhere! (wash your hands!)

  11. Kingdom Protista • Eukaryotic • Unicellular & Multicellular • Some with cell walls with cellulose, some without • Some autotrophic, some heterotrohpic • Mostly aquatic

  12. Kingdom Fungi • Eukaryotic • mostly Multicellular, some unicellular • Cell walls with chitin • Heterotrohpic • Mostly terrestrial

  13. Kingdom Plantae • Eukaryotic • all Multicellular • Cell walls with cellulose • Autotrophic • Terrestrial and aquatic

  14. Kingdom Animalia • Eukaryotic • all Multicellular • No cell walls • Heterotrophic • Terrestrial and aquatic

  15. Let’s Review • What are the determinant criteria for Kingdoms? • ___________________________ • (unicellular vs. multicellular) • ___________________________ • (prokaryotic vs. eukaryotic) • ___________________________ • (composition of cell wall vs. no cell wall) • ___________________________ • (autotrophic vs. heterotrophic)
