They are also necessary to the energy exchange that living things need to survive. Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy. Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose. Photosynthesis takes place in the chloroplasts of cells. In many respects, photosynthesis and cell respiration are complementary reactions within the environment.
Most producers i. Interrelationship Between Processes. Photosynthesis and cell respiration both involve the production of chemical energy ATP. In both cases, the production of ATP involves an electron transport chain and chemiosmosis. Comparison of ATP Production. Photosynthesis and cell respiration are in many respects the reverse of one another.
Differences Between Photosynthesis and Cell Respiration. Brent Cornell. Cell Introduction 2. Cell Structure 3. Membrane Structure 4. Membrane Transport 5. Origin of Cells 6. Processes in photosynthesis are divided on basis of requirement of sunlight while respiration processes are divided on basis of requirement of oxygen.
Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide.
In the dark reactions, carbon molecules now independent of oxygen are converted into carbohydrates and stored in plant cells as energy and food source. In aerobic cellular respiration oxygen is utilized to convert organic compounds into energy and in anaerobic respiration converts organic compounds into energy without using oxygen. Photosynthesis takes place in the chloroplasts and organelles of a plant cell. Respiration takes place in the cytoplasm and mitochondria in the cell of a living organism.
In cellular respiration reaction 36 molecules of ATP are produced in complete oxidation of one molecule of glucose. Share this comparison:. If you read this far, you should follow us:. Diffen LLC, n. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. To emphasize this point even more, the equation for photosynthesis is the opposite of cellular respiration.
Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival. The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration.
The carbon dioxide produced during respiration is released from the body and absorbed by plants to help provide the energy they need for growth and development.
