  1. Chapter 13: part 2 Prokaryotes and Viruses

  2. 2nd major group of Photosynthetic Bacteria • Purple and Green Bacteria Have Unique types of Photosynthesis • Purple or green sulfur bacteria- -Carbon dioxide + Hydrogen sulfide in the presence of light forms carbohydrate + water and sulfur p247. • Cyanobacteria- -Carbon dioxide+ water in the presence of light form carbohydrates+ water and oxygen

  3. Spiroplasmas- motile bacteria that cause stubborn disease

  4. Mycoplasmalike Organisms- slow weakening

  5. Mycoplasmiclike organism devestated a grove of Coconut palms

  6. Bacterial effects on Plants

  7. Halophiles- salt loving Archaea

  8. Methane producing archae

  9. Extreme thermophiles- archaea YNP HS rich

  10. General life cycle of a virus Two stages 1. Replication inside host 2. Spread to new host

  11. Tobacco Mosaic Virus

  12. Wound tumor virus Tumor produced in sweet clover

  13. Electron Microscope Tumor virus particles

  14. Streaked flowers of Rembrant tulips Viral infection eventually weakens plant
