WebApr 8, 2024 · What Is the Definition of Solute Potential? Solute potential is defined as the pressure that must be applied to a solution to prevent the inward flow of water through a semipermeable membrane. The flow of water stops because the pressure of the solution and the pressure of the water are equal. Osmotic potential is another term for solute … Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension). The concept of water potential has proved useful in understanding and computing water movement within plants, animals, and soil. Water potential is typically expresse…
