Transpiration helps regulate plant temperature by evaporating water from the leaf surfaces. This evaporative cooling process reduces leaf temperature and helps prevent overheating, particularly in hot environments.
Transpiration aids in temperature regulation in plants through the cooling effect known as evaporative cooling. As water evaporates from the stomata in the leaves during transpiration, it absorbs heat energy from the surrounding tissues. This energy absorption results in a cooling effect, similar to how sweating cools the human body. Transpiration helps prevent overheating in plants, especially in high-temperature environments. The process allows plants to dissipate excess heat, maintain optimal physiological temperatures, and prevent damage from heat stress. Additionally, the cooling effect contributes to the regulation of stomatal opening and closure, optimizing gas exchange and water conservation.
