EVERYDAY SCIENCE

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.

Detailed explanation-2: -Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.

Detailed explanation-3: -Oxygen is produced during cellular respiration and stored during photosynthesis.

Detailed explanation-4: -Carbon dioxide is a reactant of photosynthesis and a product of cellular respiration.

Detailed explanation-5: -The products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)
