  1. Diversity of Living Organisms Mr. Jeff Peterson Fulbright Teacher from Indiana, USA

  2. Diversity of Living Organisms • Biodiversity • 10 million species • 1 – 2 million known

  3. Diversity of Living Organisms

  4. Diversity of Living Organisms

  5. Diversity of Living Organisms • Too many to look at all species • Look at similarities among organisms • Similar living things grouped together • Classification • Taxonomy • study of classification

  6. Diversity of Living Organisms • Aristotle – classified animals on where they lived. • Examples: Land, Water, and Air • Problems?

  7. Diversity of Living Organisms • Carl Linnaeus • Groups based on similar and shared structures

  8. Diversity of Living Organisms • Broad divisions based on characteristics • Form and function • Uses phylogeny or the evolutionary history of an organism. • Organisms with similar internal and external features are grouped closely together.

  9. Diversity of Living Organisms • Presence of membrane bound organelles?

  10. Diversity of Living Organisms • Unicellular or multicellular?

  11. Diversity of Living Organisms • Autotroph or Heterotroph?

  12. Diversity of Living Organisms • Autotrophic plants

  13. Diversity of Living Organisms • Heterotrophic Animals • Body development and organization

  14. Diversity of Living Organisms • Based on your prior understanding of living things and what was just said about classification, make a simple diagram of all living things on Earth.

  15. Diversity of Living Organisms • Example:
