Rates of transpiration


From the set of results I have discovered that the rate of transpiration is faster in windy conditions compared to humid conditions. In windy conditions the time taken for the bubble to move 100mm was only 4 minutes when in humid conditions it took 13 minutes. In the control conditions it took 6 minutes. Transpiration is the loss of water vapour by diffusion through the stomata in the leaves. Several weather conditions affect the rate of transpiration including temperature, humidity, air movement and light intensity. The ...
