1. Photosynthesis & Respiration

2. Photosynthesis The process is a chemical reaction.

3. Chemical Equation for photosynthesis Light energy + carbon dioxide + water  glucose + oxygen

4. Why is this important to us? We cannot make our own food (glucose, energy) We must get our food from plants.

5. The oxygen released during photosynthesis is necessary for all living things.

6. Cellular Respiration Basically, it is breathing! The release of chemical energy for use by cells.

7. Chemical Equation for Cellular Respiration glucose + oxygen  energy + carbon dioxide + water (opposite of photosynthesis)
