Which process do plants use to convert light energy into sugars?

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

Answer: (A)

Plants convert light energy into sugars through photosynthesis. Chlorophyll in the chloroplasts captures sunlight and drives reactions that use carbon dioxide and water to make glucose, releasing oxygen along the way. The process has two stages: the light-dependent reactions produce energy carriers (ATP and NADPH), and the Calvin cycle uses those to fix CO2 into sugar molecules. This is how plants store solar energy in chemical form as sugars that fuel growth and metabolism. Other terms describe different processes: fermentation generates energy from sugars without light, transpiration is just water loss from leaves, and respiration breaks down sugars to release energy using oxygen. The essential idea is that capturing light energy for building sugars is what photosynthesis does.
