ETYM French transpiration.
The loss of water from a plant by evaporation. Most water is lost from the leaves through pores known as stomata, whose primary function is to allow gas exchange between the plant's internal tissues and the atmosphere. Transpiration from the leaf surfaces causes a continuous upward flow of water from the roots via the xylem, which is known as the transpiration stream.
A single corn plant has been estimated to transpire 65 gal/245 l of water in one growing season.
1. The emission of water vapor from the leaves of plants.
