WebThe rest is supplied by evaporation and the water cycle. Transpiration is a biological process necessary for plant life which uses about 90% of the water absorbed by the roots of the plant. Only about 10% of the water taken up is used for chemical reactions and tissue formation in the plant. How Transpiration Occurs. WebTranspiration serves to evaporatively cool plants, as the evaporating water carries away heat energy due to its large latent heat of vaporization of 2260 kJ per liter.
