Which process converts light energy into chemical energy in plants?

Plants convert light energy into chemical energy through photosynthesis. In chloroplasts, light energy is captured by chlorophyll and used in the light-dependent reactions to split water, releasing oxygen and producing ATP and NADPH. Those energy carriers then power the Calvin cycle, which fixes carbon dioxide into glucose. The glucose stores chemical energy that the plant can later use for growth and metabolic activities. In short, photosynthesis builds chemical energy from light. Transpiration is just water loss, respiration releases energy from stored sugars, and fermentation is an anaerobic process that provides much less energy.
