  1. Photosynthesis The capture of light energy to make carbohydrate from carbon dioxide and water

  2. Why Study Photosynthesis? • Photosynthesis and food • Photosynthesis and energy • Photosynthesis, fiber, and material • Photosynthesis and environment • Photosynthesis, technology, and medicine

  3. Photosynthetic Organisms • Plants • Algae • Cyanobacteria

  4. Overview of Photosynthesis 6 H2O + 6 CO2 ==> C6H12O6 + 6 O2 water + carbon dioxide ==> sugar + oxygen

  5. Oxygen Cycle • Most abundant element in the earth’s curst. • It account for 89% of the ocean’s mass. • Material exchanges between the atmosphere and living organisms at the earth's surface or in the ocean • Isotope O18/O16
