Answer 1

Water is Reduced.

Explanation:

• During the cycle of photosynthesis, carbon dioxide is reduced while the water is oxidized.
• In other words, carbon dioxide receives electrons and oxygen loses electrons.  
• After the reduction of carbon dioxide and oxidation of water, oxygen is produced along with glucose.
• Solar energy is used to transfer electrons from water to carbon dioxide, to produce glucose molecules.
