Solution

Root pressure
The ascent of sap is essential for supplying water and minerals to the shoot system, especially the leaves to facilitate photosynthesis.
Root pressure is a positive pressure of around 1 -2 atm.
It develops in the xylem vessels of many herbaceous plants due to more water passing into them than the utilization is the shoot system.
Root pressure pushes water upwardly when there is little transpiration.
It develops due to the metabolic activity in the roots.
Positive pressure developed in the xylem channels due to metabolic activity of the root is called root pressure.
