Plants Exchange Gas With The Atmosphere. The exchange of oxygen and carbon dioxide in the leaf as well as the loss of water vapor in transpiration occurs through pores called stomatasingular stoma. Gas exchange is needed to provide cells with enough oxygen for cellular respiration and to remove the carbon dioxide that the cells produce.

The exchange of oxygen and carbon dioxide in the leaf as well as the loss of water vapor in transpiration occurs through pores called stomata singular stoma. The exchange of gases between living plants and the atmosphere is critical to the survival of all living organisms.
This means that the net gas exchange from a leaf depends on the light intensity.
They also help to reduce water loss by closing. The immediate cause is a change in the turgorof the guard cells. Breathing is different from respiration. The structures that allow plants to exchange the gases involved in photosynthesis with the atmosphere C.
