Water potential in a plant cell refers to the push or force of water molecules moving in and out of the cell. It is like a pressure that determines how water moves within the plant, such as from the roots to the leaves. It is important for the plant to maintain the right water potential to stay healthy and function properly. Determining the water potential in a plant cells water prevents the cells from bursting but the pressure doesn’t build up inside the cell and affect the process of osmosis. When the pressure inside the cell becomes the larger enough, no additional water will accumulate in the cell even. So the movement of the water through the tissue cannot be predicted simply through knowing the relative solute concentration on the other side if the plant cell wall. Instead, the concept of water potential is used to predict the direction in which water will diffuse through the living plant tissue.

Water potential is expressed in a bar metric unit of pressure equal to 1 atmosphere and measured in barometer.
Consider the potato cell is placed in a pure water, initially, the water potential outside the cell is 0 and is higher than the water potential inside the cell. Under this condition, there will be a net movement of water into the cell. The pressure potential inside the cell will increase until the cell reaches a state of equilibrium.
using the above information, write a good introduction for the practical in ten sentences with some simple English words. do not use first, second and third person pronoun in a introduction

In this practical, we will explore the concept of water potential in plant cells. Water potential refers to the pressure of water molecules moving in and out of a cell. It is crucial for plants to maintain the correct water potential to ensure proper functioning. This pressure determines the movement of water within the plant, from roots to leaves. By understanding water potential, we can predict the direction in which water will diffuse through living plant tissue. Water potential is measured using a barometric unit of pressure, equivalent to 1 atmosphere. When a plant cell is placed in pure water, a net movement of water occurs until equilibrium is reached. This practical will provide hands-on experience in observing and understanding water potential in plant cells.
