Detailed explanation-1: -The reactants of photosynthesis are carbon dioxide and water.

Detailed explanation-2: -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-3: -Yes, water is a byproduct of photosynthesis. Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidised within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons.

Detailed explanation-4: -Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. The oxygen molecules released into the atmosphere come exclusively from the original water molecules, not from the carbon dioxide molecules.

Detailed explanation-5: -During photosynthesis, light energy (sunlight) combines with the reactants-water and carbon dioxide-to form new products: glucose (sugar) and oxygen.
