Detailed explanation-1: -Wind – Wind can alter rates of transpiration by removing the boundary layer, that still layer of water vapor hugging the surface of leaves. Wind increases the movement of water from the leaf surface when it reduces the boundary layer, because the path for water to reach the atmosphere is shorter.

Detailed explanation-2: -As the wind blows faster, the water released by transpiration is carried away faster. So, rate of transpiration increases with velocity of wind speed.

Detailed explanation-3: -The rise in temperature causes an increase in the evaporation of water from the surface of leaves. This results in an increased demand for water by the plants, leading to an increased transpiration rate. The optimum temperature for plants in the temperate climate lies between 20-30 degree Celsius.
