in the leaf
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
stomata, Lenticals and the thin coverings of roots
The volume of air that cannot undergo gas exchange is known as dead space. It consists of the air in the conducting airways (trachea, bronchi, bronchioles) where gas exchange does not occur because it does not reach the alveoli where oxygen and carbon dioxide exchange takes place.
It is because Co2(carbon dioxide) is transferred to the plant and the plant makes the Co2 Oxygen.
The leaves.
During the stage of photosynthesis, the exchange of gases occur in the leaves.
The gas occurs by simple diffusion through the cells.
