AP BIOLOGY

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: -In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration".

Detailed explanation-3: -The energy within the ATP molecule produced during cellular respiration allows photosynthesis to continue. The two processes occur simultaneously, and continuously with variations, throughout the life span of a green plant.

Detailed explanation-4: -Cellular respiration occurs in both plants and animals cells while photosynthesis only occurs in plant cells.

Detailed explanation-5: -Photosynthesis occurs only in the chloroplasts of a cell. Cellular respiration is the opposite process where plants and animals break down oxygen and glucose into water, carbon dioxide, and ATP used for energy. Cellular respiration happens in the mitochondria of both plants and animals.
