Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>
Explanation:
Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP. The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.
