Water potential is a measure of the potential energy of water in a system and determines the direction of water movement. It is the sum of several components that influence the flow of water in plants. The main components of water potential include: 1. Solute Potential (Ψs): This component results from the presence of solutes in water. Solutes lower the water potential of a solution, making it more negative. The greater the concentration of solutes, the lower (more negative) the solute potential. Pure water has a solute potential of zero, and the addition of solutes reduces the water potential. 2. Pressure Potential (Ψp): Also known as turgor pressure, it is the pressure exerted by the cell wall on the water
