solute potential

Solute potential, also known as osmotic potential, measures how much a substance’s dissolved particles lower the water’s tendency to move or flow. Imagine adding salt or sugar to water: the more particles you add, the harder it is for water to move into the solution. A higher concentration of dissolved substances results in a more negative solute potential. It’s an important factor in biology because it influences how water moves in and out of cells and tissues, helping maintain proper function and balance within organisms.
