Detailed explanation-1: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-2: -Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Detailed explanation-3: -Cellular respiration and photosynthesis depend upon each other because the reactants of cellular respiration are oxygen and glucose, and the products are water and carbon dioxide. In contrast, the reactants of the photosynthesis process are carbon dioxide and water, which are the products of cellular respiration.

Detailed explanation-4: -They both also involve an electron transport chain that helps generate ATP. Both cellular respiration and photosynthesis involve carbon dioxide, oxygen, ATP, electron carriers, and water. However, cellular respiration produces energy for the cell, whereas photosynthesis produces glucose, or food for the cell.
