Detailed explanation-1: -Final answer: Age of plant does not affect the rate of transpiration.
Detailed explanation-2: -As the relative humidity of the air surrounding the plant rises the transpiration rate decreases. It is easier for water to evaporate into dryer air than into more saturated air.
Detailed explanation-3: -Transpiration rate increases with the velocity of wind and intensity of light. As the humidity of the outside atmosphere is increased, transpiration decreases.
Detailed explanation-4: -When the relative humidity is high, the atmosphere contains more moisture. This lowers the driving force for transpiration. Lower relative humidity levels correspond to less moisture in the atmosphere and thus a higher driving factor for transpiration.
