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

In this practical, we will be investigating the concept of water potential in plant cells. Water potential refers to the force of water molecules moving in and out of a cell. It is crucial for plants to maintain the right water potential to stay healthy and function properly. The pressure of water potential determines how water moves within the plant, such as from the roots to the leaves. A barometric unit of pressure, equal to 1 atmosphere, is used to measure water potential. In our experiment, we will be using potato cells placed in pure water to observe the movement of water into the cells. By understanding water potential, we can predict the direction in which water will diffuse through plant tissue. This practical will help us better comprehend the importance of water potential in maintaining the health of plant cells. By the end of this experiment, we will have a clearer understanding of how water potential affects the movement of water in plants.
