Explanation:
Detailed explanation-1: -Transpiration is the evaporation of water from plants that occurs in the leaves during photosynthesis, when stomata open and CO2 and O2 pass through. As the temperature rises, the water evaporates faster, so plants sweat faster at higher temperatures.
Detailed explanation-2: -Temperature plays a major role in the rate of transpiration. As the temperature increases, transpiration will increase due to a higher concentration in sunlight and warm air.
Detailed explanation-3: -Transpiration results in water scarcity that can damage the plants due to desiccation. It also causes wilting of the leaves and results in stunted growth of the plants.
