ANATOMY

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -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!)

Detailed explanation-3: -During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).

Detailed explanation-4: -In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Detailed explanation-5: -Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.
