Light+CO2+Water=O2+Glucose

• Photosynthesis is the process of using light to make chemicals useful to all living organisms.
• Light energy from the sun is turned into chemical energy and stored in a plant so that it may grow larger.
• More oxygen than the plant needs is made so excess oxygen is released into the atmosphere.
• As a result oxygen males up roughly 20% of all gases in our air.
