Question

what role does sunlight play in the process of photosynthesis? it breaks down glucose into water molecules. it is converted into usable chemical energy. it releases oxygen molecules from water.

Explanation:

• Analyze Option 1: Breaking down glucose into water is part of cellular respiration, not photosynthesis, so this is incorrect.
• Analyze Option 2: In photosynthesis, sunlight (light energy) is absorbed by chlorophyll and converted into chemical energy (stored in glucose), which matches the role of sunlight.
• Analyze Option 3: The release of oxygen from water is a result of the photolysis of water, but the primary role of sunlight is energy conversion, not just oxygen release from water. So this is not the main role.

Answer:

B. It is converted into usable chemical energy.
