Movement of Water Out of the Plant-Soil System,our in the foliage or at the surface of the soil. By far the largest part of this energy enters as shortwave radiation from the sun. A comparatively small component comes in as advective energy, that is energy derived from a change in the temperature of the air as it passes over the evaporating or t

These conditions are t

Its movement up the plant depends on the water having sufficient cohesion to remain in intact columns in spite of the tension exerted by removal (evaporation) of water from their upper ends. This concept is therefore known as the cohesion-tension theory.

Water Within the Plant, most successful of root pressure demonstrations. The rate of exudation from a detopped plant is usually only of the order of 5 per cent of the previous transpiration rate of the intact plant. Thus osmotic uptake of water into the roots cannot explain the flow of water to the tops of trees.
