उत्तर

Transpiration takes place through stomata. Transpiration factor is mainly dependent on the number of stomata, percent of open stomata, water availability and structure of canopy etc. these factors may differ in different plants. So the different plant species in the same area cannot show the same transpiration rate. It may differ in different species at a particular time.
