Due to root pressure, the water rises through the plant stem to the leaves. Absorption of water and minerals by plants directly depends on the transpiration pull generated by loss of water through stomata but transportation of sugars from source to sink is a physiological process and is not related to transpiration loss of water. the Transpiration Pull is the biological force generated by plants to draw the water upwards from roots to leaves through xylem tissues. . As a result, it promotes cell division and organ growth. In extreme circumstances, root pressure results in guttation, or secretion of water droplets from stomata in the leaves.
