Transpiration refers to the loss of water vapour via the stomata by diffusion. Note that this is different to the transpiration stream which is the movement of water from the roots to the leaves. Transpiration is important to the plant in the following ways. It provides a means of cooling the plant via evaporative cooling.. Because cooler air holds less water, its relative humidity increases or it is 'moister air'. Therefore, warmer air will increase the driving force for transpiration and cooler air will decrease the driving force for transpiration. Soil water - The source of water for transpiration out of the plant comes from the soil.

5.3 Transpiration (ESG7J) This section explains how various environmental factors can change the rate of transpiration, and also examines how the structure of the leaves has adapted to minimise this water loss. Learners will need to understand the factors that affect the transpiration rate such as temperature, light intensity, wind and humidity.. Climate change can affect transpiration by altering solar irradiance, wind patterns, surface temperatures, humidity levels, plant species compositions and the distribution of precipitation. Rising.
