Which process do plants use to convert sunlight into food?

• A. Respiration
• B. Transpiration
• C. Photosynthesis
• D. Fermentation

Answer: (C)

Plants convert sunlight into food through photosynthesis, a process that captures light energy and uses it to build sugars from carbon dioxide and water. In the chloroplasts, light energy drives reactions that split water and generate energy carriers (ATP and NADPH). Those energy molecules power the Calvin cycle, which fixes carbon dioxide into glucose. This stored chemical energy in sugar fuels growth and life processes. The other processes don’t create food from light: respiration breaks down sugars to release energy, transpiration is the loss of water from the plant, and fermentation provides energy without using light and typically in low-oxygen conditions.
