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 converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
Detailed explanation-3: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.
Detailed explanation-4: -The reactants of photosynthesis are sunlight, CO2, and water (H2O). The products of photosynthesis are glucose (C6H12O6) and oxygen (O2). The reactants of cellular respiration, which are the products of cellular respiration, are carbon dioxide (CO2), water (H2O), and ATP.
Detailed explanation-5: -During oxygenic photosynthesis, light energy transfers electrons from water (H2O) taken up by plant roots to CO2 to produce carbohydrates. In this transfer, the CO2 is “reduced, ” or receives electrons, and the water is “oxidized, ” or loses electrons. Oxygen is produced along with carbohydrates.
