• A. Water is reduced and CO₂ is oxidized
• B. Both CO₂ and water are produced
• C. Both CO₂ and water are oxidized
• D. CO₂ is reduced and water is oxidized

Answer 1

The correct option is D CO₂ is reduced and water is oxidized

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.
