Final answer:
During photosynthesis, carbon dioxide and water are indeed used to form glucose in the presence of light, along with oxygen as a by-product. It is a crucial process in which energy from sunlight is stored as chemical energy in carbohydrates.
Step-by-step explanation:
True. During photosynthesis, carbon dioxide and water, in the presence of light, are used to form glucose. This biological process is essential for plant life and contributes to the energy cycle of all living organisms. In the chloroplasts of plant cells, photosynthesis transforms solar energy into chemical energy by producing glucose and releasing oxygen as a waste product. The overall equation for this process can be summarized as: carbon dioxide (CO₂) + water (H₂O) → glucose (C₆H₁₂O₆) + oxygen (O₂).
Photosynthesis is not only about the formation of glucose but also the creation of oxygen, which is vital for animal life. Through a series of reactions involving light energy, ATP, and NADPH produced in the light reactions, and carbon dioxide, the Calvin Cycle synthesizes glucose. This demonstrates how through photosynthesis, plants convert low-energy molecules (carbon dioxide and water) into high-energy molecules (glucose), thereby storing energy in the form of carbohydrates.
