Detailed explanation-1: -Final answer: Age of plant does not affect the rate of transpiration.
Detailed explanation-2: -In terms of transpiration, or plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open as much. This means that, at the scale of a leaf, less water is lost and there is lower transpiration.
Detailed explanation-3: -Chlorophyll content of leaves does not directly affect rate of transpiration.
Detailed explanation-4: -Transpiration is the process by which plants lose water in the form of water vapour mainly from stomata present on their leaf surface. Conditions that increase the rate of transpiration include increase in temperature, decrease in humidity, increase in wind speed, and more.
