Answer:
On a simplified level, photosynthesis and cellular respiration are opposite reactions of each other. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
Answer: Photosynthesis
Explanation: Cell respiration and photosynthesis are essentially opposite processes. Photosynthesis is the process by which organisms make high-energy compounds – the sugar glucose in particular – through the chemical "reduction" of carbon dioxide (CO2).
