So we have a high osmotic potential, a low osmotic potential. And what that means is water will begin to naturally move down its osmotic potential gradient from the left side to the right side in the same analogous way that the marker will move down its gravitational potential gradient. So once again, suppose the left side only contains pure water while the right side contains water. Along with some solute molecules shown in green. The two sides are separated by a semipermeable membrane that only allows water to move across. Now, since pure water has an asthmatic pressure and an osmotic potential of zero, but the right side has a more negative osmotic potential, so it's smaller osmotic potential.
