Root pressure is responsible for pushing up water to small heights in the stem. The greatest
contribution of root pressure may he to re-establish the continuous chain of water molecules in the xylem, which often break under the enormous tensions created by transpiration. Root pressure does not account for the majority of water transport, most plants meet their need by transpiratory pull.
