WebHumidity: Increasing the humidity is predicted to cause a decrease in the rate of transpiration. Humidity is the amount of water vapour in the air – less vapour will diffuse from the leaf if there is more vapour in the air. The effect of humidity can be tested experimentally by encasing the plant in a plastic bag with variable levels of vapour. Webtranspiration enhances nutrient uptake into plants. Carbon dioxide entry: When a plant is transpiring, its stomata are open, allowing gas exchange between the atmosphere and the leaf. Open stomata allow water vapor to leave the leaf but also allow carbon dioxide (CO 2) to enter. Carbon dioxide is needed for photosynthesis to operate.

WebMay 14, 2024 · In angiosperms and gymnosperms (but not in ferns and lycopsids), Abscisic acid (ABA) is the hormone that triggers closing of the stomata when soil water is insufficient to keep up with transpiration (which often occurs around mid-day). The mechanism: ABA binds to receptors at the surface of the plasma membrane of the guard cells. WebWhat are the 3 factors that affect transpiration rate?
