How do plants stay cool by evaporation?

Plants stay cool by a process called transpiration, where water evaporates from tiny openings called stomata on their leaves. As water evaporates, it absorbs heat from the plant and the surrounding air, reducing the plant's temperature. This cooling effect helps maintain optimal conditions for photosynthesis and overall plant health. Additionally, the loss of water through transpiration creates a negative pressure that aids in the uptake of water and nutrients from the roots.
