Detailed explanation-1: -Oxygen and water are the raw materials for photosynthesis.
Detailed explanation-2: -Thus, the correct answer is ‘Carbon dioxide, water, and sunlight’.
Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Detailed explanation-4: -The conversion of sunlight into usable chemical substances is attained by chlorophyll. The raw materials needed for the process of photosynthesis are CO2 and H2O. 6 molecules of water and 6 molecules of carbon dioxide with the help of sunlight produce glucose and 6 molecules of oxygen.
Detailed explanation-5: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
