Q. During photosynthesis, green plants use energy from sunlight to synthesize ___ from carbon dioxide and water:
Answer: Glucose
Notes: Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxy-gen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.
