Summary. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water
Most plants appear green because they absorb all other colors of light and reflect back green into our eyes. Since chlorophyll molecules use the red (opposite of green) end of the visible light spectrum to complete photosynthesis, then red is most heavily absorbed.
