Under normal conditions, plants maintain a stable internal temperature through a process called homeostasis. This regulation is mainly achieved through the process of transpiration, where plants release water vapor from their leaves. Transpiration helps to cool down the plant and maintain an optimum temperature for its metabolic processes.
During drought stress, however, the availability of water becomes limited, and transpiration is significantly reduced. As a result, the cooling effect of transpiration decreases, leading to an increase in the plant's temperature. Without sufficient water, plants cannot regulate their temperature as effectively, which can have negative impacts on their physiological functions and overall health.
Therefore, under drought stress, the temperature of plants increases due to the reduced availability of water to facilitate transpiration and maintain their normal temperature.
Why is the temperature of plants under normal conditions the same as plants under drought stress
