How does light influence water movement? (multiple answers may be correct)
Light stimulates stomatal opening, allowing water vapor to easily leave the leaf.
Light also speeds up transpiration by warming the leaf.
Light stimulates stomata to close, stopping water vapor from leaving the leaf.
Light also slows down transpiration by warming the leaf.
How does wind influence water movement? (multiple answers may be correct)
Increased movement of the air around a plant (wind) will result in a higher transpiration rate.
Wind will move the air around, with the result that the more saturated air close to the leaf is replaced by drier air.
Increased movement of the air around a plant (wind) will result in a lower transpiration rate.
Wind will move the air around, with the result that the more drier air close to the leaf is replaced by saturated air.
