What are aquaporins in osmosis? (shadowebike.com)
If a molecule is not able to cross a semipermeable membrane, water will diffuse by osmosis until the concentrations of molecules are equal on both sides. (eonslearning.org)

In osmosis, if the particles can't move for some reason, water moves from where particles are at a low concentration to where particles are at a high concentration. (eonslearning.org)
Diffusion and osmosis are really just variations of the same idea: Whenever any molecule (a particle or water) can move, it will move until it is as uncrowded as possible, like by moving to the other side of a semipermeable membrane until the concentrations on both sides are equal.
