They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like … WebThis condition causes the leaf to lose turgor or firmness, and the stomata to close. If this loss of turgor continues throughout the plant, the plant will wilt. Light – Stomata are triggered to open in the light so that carbon dioxide is available for the light-dependent process of photosynthesis.

WebThe shape of guard cells and the presence of subsidiary cells are also suggested to impact on stomatal responses (as discussed in “Stomatal morphology and improved WUE” below). In addition, the distribution of stomata between leaf abaxial and adaxial surfaces may also affect plant responses to environmental stresses. WebLight is one factor that affects the rate of photosynthesis. For example, if light intensity is decreased, this will result in a decrease in the rate of photosynthesis. heath llcWebIt does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange. movies on investment banking
