  1. CO 7 Photosynthesis

  2. What is a plant anyway? Photosynthetic Organisms A. Photosynthesis transforms ___________ B. Organic molecules built by photosynthesis provide both the building blocks and _____ for cells.

  3. Figure 7.1b C. Plants use the raw materials: ___________and ______ D. __________ carry out photosynthesis

  4. Figure 7.1c E. Chlorophylls and other pigments involved in absorption of solar energy reside within ____________________of chloroplasts

  5. Figure 7.2

  6. Quick Check – 1.  Plant 2.  Thylakoid 3.  Photosynthesis 4.  Organic Molecules Two words that sound alike but are not at all similar: Stroma Stoma

  7. Plants as Solar Energy ConvertersA. Solar Radiation - Only 42% of solar radiation that hits the earth’s atmosphere reaches surface; most is visible light.

  8. B. Photosynthetic Pigments - Pigments found in chlorophyll absorb various portions of visible light; absorption spectrum. 1. Two major photosynthetic pigments are _______ and ___________.2. Both chlorophylls absorb violet, blue, and red wavelengths best.3.  Most green is reflected back

  9. 4. Carotenoids are yellow-orange pigments which absorb light in violet, blue, and green regions.

  10. Fall Foliage Slideshow

  11. Checkpoint A radish plant is grown behind using lights of different colors. Explain the chart.

  12. D. Photosynthetic Reaction 1. In 1930 C. B. van Niel showed that O2 given off by photosynthesis comes from water and not from CO2.2. The net equation reads:

  13. E. Two Sets of Reactions in Photosynthesis1. Light reactions cannot take place unless light is present. They are the energy-capturing reactions.

  14. 2. Calvin Cycle Reactions a. These reactions take place in the _____; can occur in either the______ or the _____ b. These are synthesis reactions that use _______ and ______to reduce CO2. -- and make a _________________

  15. Quick Practice

  16. What you should know by now.. 1.  The equation for photosynthesis.  Write it! 2.  The structure of a chloroplast.  Sketch it! 3.  The two reactions of photosynthesis.

  17. What Factors the Affect Photosynthesis? 1. Light Quality (color) 2. Light intensity 3. Light Period 4. Carbon Dioxide Availability 5. Water Availability *Design an experiment to test ONE of the above factors* Photosynthesis Simulation Waterweed Simulator
