Explanation:

Cellular respiration in mitochondria produces carbon - dioxide and water, and consumes glucose and oxygen. Photosynthesis in chloroplasts consumes carbon - dioxide and water, and produces glucose and oxygen. Carbon dioxide is produced in cellular respiration and is a reactant of photosynthesis. Glucose is produced in photosynthesis and is a reactant of cellular respiration.

Answer:
