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-Dependent Reactions

  9. Light-Independent Reactions

  10. Please note that due to differing operating systems, some animations will not appear until the presentation is viewed in Presentation Mode (Slide Show view). You may see blank slides in the “Normal” or “Slide Sorter” views. All animations will appear after viewing in Presentation Mode and playing each animation. Most animations will require the latest version of the Flash Player, which is available at http://get.adobe.com/flashplayer.

  11. Hydrothermal Vents- Chapters 2, 5, 16

  12. 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.
