Stomata open in the light and close in the dark when transpiration is at its lowest. Higher light intensity increases rate of transpiration. Lower light intensity lowers rate of transpiration.

How does temperature affect rate of transpiration?
Temperature alters the kinetic energy of the water molecules and the relative humidity of the air. Higher temperatures increase rate of transpiration. Low temperatures decrease rate of transpiration.
3 of 5
How does humidity affect rate of transpiration?
Humidity affects the water potential gradient between the air-spaces in the leaf and the atmosphere. Lower humidity increases rate of transpiration. Higher humidity decreases rate of transpiration.

How does air movement affect rate of transpiration?
Air movement changes the water potential gradient by altering the rate at which moist air is removed from around the leaf. More air movement increases rate of transpiration. Less air movement decreases rate of transpiration.
