Root pressure is a pressure in the xylem due to metabolic activity of the root cell. It is a hydrostatic pressure developed in the root system that pumps the water or sap in the root xylem. Root pressure helps in re-establishing the continuous chain of water molecules in the xylem. This pressure pushes the water up into small heights
Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.

Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground. It is partially responsible for the rise of water in plants.
The root pressure is the pressure which is exerted on the liquid contents of the fully turgid cortex cells of the root, forcing some of it into the xylem vessels and up through the stem. It is a vital phenomenon and depends upon the activity of the living cells of the root. This is the osmotic pressure which causes the water in the xylem to travel in the upward direction. This is necessary for supplying the cells of the plants with water and the mineral nutrients. This pressure is responsible for the absorption of water and the essential minerals from the soil.

Here's your answer
ROOT PRESSURE is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.
Root pressure is also linked to the phenomenon of guttation, i.e., the loss of water in the form of liquid droplets from the vein endings of certain herbaceous plants.
Root pressure is only able to transport water up to small heights. However, it helps in re-establishing the continuous chains of water molecules in the xylem. Transpirational pull maintains the flow of water molecules from the roots to the shoots.

It is helpful to longest plants to supply of water to the tip of the plant with the help of roots and stem
think it will help little bit
NCERT based answer for Class 11 Biology Students
Root pressure is the force that helps to drive fluids upward in the xylem. It is primarily generated by osmotic pressure in the cells of roots and can be demonstrated by exudation of fluid when a young stem is cut off just above the ground.
Effect of root pressure is observable at night and early morning when evaporation is low.
Excess water collects in the form of droplets around openings of vein near tip of grass blades. Such water loss in the liquid phase is known as guttation.
Mineral ions from soil are taken up by roots and get accumulated in xylem vessel by active transport.
Accumulation of ions leads to increased osmotic potential in root cells and low water potential in xylem vessels.
Low water potential of xylem sap compared to that of soil solution makes water move inside the roots. This increases pressure inside xylem; known as root pressure.
Usefulness of Root Pressure:
The greatest contribution of root pressure is to re-establish continuous column of water in xylem which often breaks under enormous tensions created by transpiration.

Root pressure is caused by active distribution of mineral nutrient ions into the root xylem. Without transpiration to carry the ions up the stem, they accumulate in the root xylem and lower the water potential. Water then diffuses from the soil into the root xylem due to osmosis.
