WebAtmospheric CO2 has been increasing rapidly since the late 1800s, largely due to human activities. Recall that CO2 enters leaves through stomata and can then be used for photosynthesis. However, transpiration occurs as a result of water evaporating through stomata. How have plants responded to elevated CO2 levels? Assuming that the CO2 … WebTranspiration is the exhalation of water vapor through the plant's stoma. Energy is not required for this movement because it is a passive process. Transpiration is important in the development of a plant because it provides nutrients and water from the roots to the leaves of the plant.
