water potential

Water potential is a measure of the tendency of water to move from one area to another, driven by factors like pressure and solute concentration. It helps explain how water moves in plants, soil, and organisms. Higher water potential means water is more likely to move into that area, while lower water potential indicates less available water. For example, pure water has the highest potential, and adding solutes or applying pressure lowers it. Water naturally moves from areas of higher to lower water potential, seeking equilibrium, which is essential for processes like nutrient transport and maintaining cell structure.
