  1. Origins of Life Review 2014 Mr. Raiz and Mrs. Kaes

  2. Compare & Contrast… Abiogenesis Biogenesis the idea of life arising from other living organisms Examples Cats make cats; humans make humans; • AKA Spontaneous Generation • the idea that life can arise from nonliving material • Examples • mice come from haystacks; • Flies from rotting meat

  3. Redi, Spallanzani, & Pasteur 3 scientists tried to disprove one theory… Who were they? What were they trying to disprove? Abiogenesis (Spontaneous Generation)

  4. What two scientists created the apparatus seen here? • Miller & Urey

  5. What theory were Miller and Urey Testing? • Oparin and Haldane’s Theory of chemical evolution

  6. Miller and Urey tried to recreate the atmosphere of… • Primitive Earth

  7. What does letter A represent? Be Specific in your description. • Represents oceans – boiling due to the high heat conditions of primitive earth • Also created water vapor which leads into the next step

  8. What were the results of the Miller Urey Experiment? (Letter E) • Amino Acids and other simple organic compounds, i.e. HCN and formaldehyde

  9. List 3 examples of energy sources on Primitive Earth • Lightning • UV Radiation • Heat

  10. Compare & Contrast… Primitive Earth Modern Earth O2 & Ozone Layer Blue Oceans Blue Skies Lots o’ life! • Lacked Free O2 • Volatile (Hot, Lightning, UV rays) • Brown Oceans • Pink Skies • No life

  11. Unicellular Prokaryotic Heterotrophic Anaerobic Protocells and primitive cells

  12. Conditions for processes that REQUIRE or USE O2 Aerobic Conditions for processes that DO NOT USE O2 ANAEROBIC

  13. 3 DOMAINS… WHAT ARE THEY? Archaea Bacteria Eukarya

  14. List the Kingdoms under Eukarya • Protists • Plantae • Animalia • Fungi

  15. List the kingdoms under Bacteria and Archaea Bacteria Archaea Archaeabacteria • Eubacteria

  16. Which Kingdoms contain Unicellular Organisms? • Eubacteria • Archaeabactia • Some Protists • Some Fungi 2 of the kingdoms are Prokaryotic… Which 2?

  17. Describe the differences between Prokaryotes and Eukaryotes… Prokaryotes Eukaryotes Contain a nucleus Multicellular (some unicellular) More complex • LACK a nucleus • Unicellular • Simple design
