Photosynthesis and Respiration are two reactions that complement each other in nature. Photosynthesis is the process by which solar energy from the sun is transformed into chemical energy. Plants use the sun's energy to create sugars, which is food for the plant. The chemical energy is stored in glucose. Carbon dioxide, sunlight, and water are taken in by plants to create glucose, oxygen, and water in the plant. This entire process occurs in the chloroplasts of the plant. In simple terms, photosynthesis is the process by which plants create their own food. Respiration is the process by which oxygen in the atmosphere outside is transported to cells in the tissue of living things. In other words, respiration is the process in which oxygen and nutrients are converted into useful energy in the cell. The oxygen from outside reacts with glucose in the mitochondria, an organelle in a plant and animal cell. This action releases ATP, water, and carbon dioxide.

Formula for Photosynthesis:

6CO2 + 6H2O ==> C6H12O6 + 6O2





Formula for Respiration:

C6H12O6 + 6O2 ----> 6CO2 + 6H20
