  1. Bacteria and Archaea The Evolutionary History of Biodiversity Concept 2: Analyzing the diversity of bacteria, archaea, protists, and fungi (Ch 26, 27, 28, 31)

  2. Bacteria and Archaea You must know: • The key ways in which prokaryotes differ from eukaryotes with respect to genome, membrane-bound organelles, size, and reproduction. • Mechanisms that contribute to genetic diversity in prokaryotes, including transformation, conjugation, transduction, and mutation. • Refer to pg 174-176 in Holtzclaw, Ch 27 in Campbell and media resources

  3. The Prokaryote • Cell Wall contains peptidoglycans • Gram-positive (simple) • Gram-negative (complex) …plus circular plasmids …or cilia

  4. Try This! Prokaryotes verses Eukaryotes

  5. Try This! Prokaryotes verses Eukaryotes

  6. The Prokaryotes: Bacteria and Archaea • The size of things • Flagella

  7. The Prokaryotes: Bacteria and Archaea • What is the difference between these two domains? • Refer to p. 173 Holtzclaw “A Comparison of the three domains of Life”

  8. The Prokaryotes: Bacteria and Archaea • What is the difference? • “A Comparison of the three domains of Life”

  9. The Prokaryotes: Bacteria and Archaea • What is the difference? • “A Comparison of the three domains of Life”

  10. Genetic Diversity in Prokaryotes • Asexual Reproduction • Binary Fission • Need mechanisms to contribute to genetic diversity • WHY? • Mechanisms for Genetic Diversity • Mutation (with rapid reproduction) • Transformation • Conjugation • Transduction

  11. Mutation (with Rapid Reproduction)

  12. Transformation

  13. Conjugation

  14. Transduction • Viruses

  15. Metabolic Diversity • Photoautotrophs • Chemoautotrophs • Photoheterotrophs • Chemioheterotrophs • Obligate aerobes • Obligate anaerobes • Facultative anaerobes • Nitrogen Fixation • Extremophiles • Extreme halophiles • Extreme thermophiles

  16. AP Themes • Chemical Recycling – Decomposers • Ecological Interactions – Symbiosis • Mutualism • Bioremediation • Your intestinal bacteria • Production of cheese, etc • Deep-sea vents • Commensalism • Parasitism • Pathogenic • Antibiotics

  17. Let’s Investigate!
