Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Advertisements: The differences between respiration and photosynthesis are: Respiration. 1. It is a catabolic process in which food material is broken down and energy is release. 2. Carbohydrates, like glucose, act as raw materials. Oxygen is required in aerobic respiration. 3. The process of respiration goes on 24 hours a day. 4. Every living cell of the organism respires. 5. The end products of respiration are H2O, CO2, and energy in form of ATP. 6. The day weight of the plant decreases due to utilization of food materials. Photosynthesis. 1. It is an anabolic process in which food material is synthesized and energy is stored.
