Transpiration – Notes
Transpiration is the loss of water due to evaporation that occurs through pores in leaves called stomata.
The opening and closing of stomata is directly impacted by the turgidity of guard cells.
The transport pull for the ascent of water in Xylem cells is made possible by three physical properties of water- cohesion, adhesion and surface tension.
Transpiration not only creates this pull for the absorption and transport of water for photosynthesis; it also transports minerals from the soil to all parts of the plant.
