I'm pretty sure that it's been proven that root pressure has very little to do with water movement in plants. Water moves up because it's constantly evaporating from the leaves and so it get sucked upwards (not pushed upwards). That is called transpiration.
cohesion,adhesion,capillary action
The term for the upward movement of water through a tiny space in response to tension is "capillary action." This phenomenon occurs due to the combination of cohesive forces between water molecules and adhesive forces between water and the surrounding material, allowing water to rise against gravity in narrow spaces, such as in soil or plant xylem.
Principle of cohesion force among water molecules
The movement of water out of the leaves of a plant is known as transpiration. This process involves the evaporation of water from small openings called stomata, which are primarily located on the leaf surfaces. Transpiration helps in regulating temperature, maintaining nutrient flow, and creating a negative pressure that aids in the upward movement of water from the roots through the xylem.
Water moves inward in the root through a process called osmosis, where it travels from the soil into root cells that have a higher solute concentration. Once inside the plant, water moves upward through the stem via capillary action in the xylem vessels, aided by transpiration, which creates a negative pressure that pulls water upward from the roots to the leaves. This combination of osmotic movement and capillary action ensures efficient water transport throughout the plant.

Some of the forces that can act on a plant include wind (which can cause movement and possibly breakage), gravity (causing the plant to grow upwards), and mechanical forces from animals or humans (such as when pruning or harvesting).

The shoot and root system of a plant interact to cause seedlings to grow upward. The shoot system contains the stem and leaves, which grow upward toward the light for photosynthesis. The root system anchors the plant and absorbs water and nutrients from the soil to support the growth of the shoot system.
Geotropism is a plant growth or movement in response to gravity. Upward growth of the plant's parts against gravity is called negative geotropism, whilst downward growth of roots is called positive geotropism.
When the plant is placed in sunlight having sufficient water to absorb, it undergoes rapid transpiration and upward movement of water (ascent of sap). This phenomenon is slowed down in dark without water.
The xylem is the part of a plant that transports water and nutrients from the roots to the stem and leaves. It consists of a network of hollow tubes that allow for the upward movement of water and minerals through capillary action.
because of water's cohesion property, which is its ability to stick to itself and it adhesion property, which mean that water can stick to other material, it can travel upward in a plant. also, the plant's tube is very small, which allow water to overcome gravity and travel upward.
Transpiration pull and cohesion-tension are the two forces responsible for most of the upward flow of water through a plant. Transpiration pull is the force generated by water evaporation from the leaves, creating tension in the xylem vessels. Cohesion-tension occurs due to the cohesion of water molecules and adhesion to the walls of xylem vessels, helping to pull water up from the roots.
If a plant is tipped on its side, the shoot will still grow upward.
