Plants respire through tiny openings or holes called stomata that are present on the underside of the leaves. Stomata trap air (like oxygen) and the exchange of gases takes place in side the plant cells.

Our body has a large percentage of oxygen in it. Oxygen is absorbed by the blood stream in the lungs, being then transported to the cells where other processes take place. Oxygen also plays a vital role in the breathing processes and in the metabolism. Nutrient compounds, inside of the cell, are oxidized through complex enzymatic processes. Oxidation is the source of energy for many organisms unless the organism is anaerobic. A quarter of the body's oxygen is used by the brain.
