Photosynthesis is the process where green plants use sunlight, carbon dioxide, and water to make food and oxygen.Respiration is the process where cells use this food to release stored energy.

Photosynthesis: 6CO2 + 6H2O + energy --> 6O2 + C6H12O6

Cellular Respiration: 6O2 + C6H12O6 --> 6H2O + 6CO2 + energy

- Sunlight produces the energy source for Photosynthesis. It uses water and carbon dioxide to make glucose. Cellular Respiration is the opposite of Photosynthesis. It breaks down glucose, using oxygen which creates water and carbon dioxide.

Results are: O2+C6H12O6->H2O+ATP+CO2
