The most important factor affecting transpiration is
Open in App
Solution
The correct option is D Atmospheric humidity
Transpiration is defined as loss of water in gaseous or vapour form through stomata. The most important factor governing rate of transpiration is the vapour pressure gradient between internal environment of leaf mesophyll tissue and the environment. Thus, the most important factor affecting transpiration is the atmospheric humidity. At high levels of atmospheric humidity, less transpiration occurs.
