Answer

The water deficit or suction force developed in leaf cells due to transpiration is responsible for pulling the water column in the upward direction (ascent of sap) . Hence, it is called transpiration pull. The magnitude of suction force is sufficient to lift the water column to any heights, even in tallest trees.
