Presentation Transcript

  1. Photosynthesis Chapter 4

  2. Photosynthesis • Photosynthesis- the production of carbohydrates from carbon dioxide and water in the presence of chlorophyll using light energy. 6CO2 + 12H2O ---> C6H12O6 + 6O2 + 6H2O

  3. Summary of Photosynthesis

  4. Light Penetration vs. Depth

  5. Albert Einstein- proposed the Particle Model of Light in 1905. • Light is composed of particles of energy called photons. • Visible light has different photon wavelengths.

  6. Absorption Spectra for Several Plant Pigments 450 430 Phycobilins- 500-660 445 480 660 410 640

  7. Seaweed and Plant Cells

  8. Light Reactions

  9. Hydrothermal Vents- Chapters 2, 5, 16

  10. Hydrothermal Vent • Hydrothermal vent- a deep-sea hot spring where heated seawater forces its way up through the crust. • Discovered rich communities in 1977. • Temperatures range from 10-20⁰C (50-68⁰F) to 350⁰C (660⁰F). • Mineral particles such as sulfides and carbonates precipitate to form chimneys.
