Notice that the equations for respiration and photosynthesis are the exact reverse: Photosynthesis light energy + carbon dioxide + water---------> oxygen + glucose Respiration oxygen + glucose----> carbon dioxide + water + energy Photosynthesis requires light energy to drive the reaction and respiration produces energy for the plant's metabolic processes.
(Photosynthesis light energy + carbon dioxide + water; requires; to drive the reaction and respiration) (light energy; to drive; the reaction and respiration)
Photosynthesis light energy + carbon dioxide + water light energy
