WHAT IS TRANSPIRATION PULL ?

Asked by  | 8th Aug, 2010, 10:48: PM

Expert Answer:

Water is transpired from the plants leaves via the stomata. It is carried there via leaf veins and vascular bundles within the plants cambium layer. The movement of water out of the leaf stomata creates, when the leaves are considered collectively, a transpiration pull. The pull is created through water surface tension within the plant cells. The draw of water upwards is assisted by the movement of water into the roots via osmosis.
