photosynthesis uses food and cellular respiration produces food

|
|
photosynthesis gives off oxygen and cellular respiration uses oxygen
|
|
|
photosynthesis uses oxygen and cellular respiration uses carbon dioxide
|
|
|
photosynthesis makes ATP and cellular respiration uses sunlight
|
Detailed explanation-1: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
Detailed explanation-2: -Photosynthesis makes glucose which is used in cellular respiration for making ATP. The glucose is then transformed back into carbon dioxide, which is used in photosynthesis. It helps cells to release and store energy.
Detailed explanation-3: -The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
Detailed explanation-4: -In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yield glucose and oxygen during the process of photosynthesis.
