In terrestrial plants, air enters the tissues, and the gases diffuse into the moisture bathing the internal cells. In the leaf of the plant, an abundant supply of carbon dioxide must be present, and oxygen from photosynthesis must be removed.

WebStomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore. This stomatal movement is affected by several environmental stimuli, such as relative humidity, CO2 concentration, and light intensity. What plants open and close? WebPart 1 describes some of the hormones that initiate and regulate plant behaviors; ... However, because closed stomata prevent gas exchange, plants will die if the stomata remain closed for too long. Thus if a drought persists for too long, the plant will begin sacrificing certain areas by allowing the leaves or stems to die in localized regions.

WebGuard cells provide the major pathway for gas exchange in higher plants; they regulate CO2 entry into, and water loss from leaves of higher plants. Thus, guard cells regulate the balance between photosynthesis and water conservation. We will use the model plant Vicia faba L. to determine how guard cells respond to atmospheric CO2 concentration. WebGas exchange allows the organisms to replenish the oxygen and eliminate the carbon dioxide. In the case of plants during photosynthesis, it allows release of oxygen and replenishment of carbon dioxide (plants also need oxygen, just like animals, for respiration).
