The production of glucose in plants is indirectly dependent on sunlight through the process of photosynthesis. During photosynthesis, plants use energy from sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced through photosynthesis is used as a source of energy and building material for the plant. Without sunlight, photosynthesis cannot occur and the plant cannot produce glucose. Thus, the production of glucose in plants is indirectly dependent on sunlight
