Detailed explanation-1: -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-2: -During photosynthesis, light energy (sunlight) combines with the reactants-water and carbon dioxide-to form new products: glucose (sugar) and oxygen.
Detailed explanation-3: -The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis.
Detailed explanation-4: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
Detailed explanation-5: -The process takes place in the plant’s chloroplasts. These special organelles are only found in photosynthetic organisms. Here, the pigment chlorophyll absorbs specific wavelengths of sunlight, allowing carbon dioxide and water to be converted into glucose and oxygen.
