8. PHOTOSYNTHESIS WHY IS THIS IMPORTANT?

9. Our planet runs on solar energy Provides us with all our food requirements and much of our fuel requirements global warming

12. Where Does Photosynthesis Happen? Photosynthesis happens in Chloroplasts Chlorophyll is the green pigment located within the chloroplasts

14. Overview of Photosynthesis Light-dependent reactions –Light energy is transferred to ATP and NADPH –Water molecules are split, releasing O 2 Light-independent reactions (Calvin Cycle) –Energy in ATP and NADPH drives synthesis of glucose and other carbohydrates from CO 2 and water
