Detailed explanation-1: -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. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

Detailed explanation-2: -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-3: -Photosynthesis uses energy from sunlight to produce glucose, and then cellular respiration breaks down glucose to release energy that can power a cell.

Detailed explanation-4: -Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes. Fun fact! Photosynthesis by microorganisms called cyanobacteria is what put oxygen into the Earth’s atmosphere in the first place.

Detailed explanation-5: -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.
