WebHumidity: Increasing the humidity is predicted to cause a decrease in the rate of transpiration. Humidity is the amount of water vapour in the air – less vapour will diffuse from the leaf if there is more vapour in the air. The effect of humidity can be tested experimentally by encasing the plant in a plastic bag with variable levels of vapour.
