Osmosis

$Osmosis is the diffusion of water molecules from an area of **high water potential** (dilute solution/high concentration of water) to an area of **low water potential** (concentrated solution/low concentration of water) through a **partially** **permeable** **membrane**.$

A partially permeable membrane is one that allows small molecules (like water) through, but not larger molecules (like solute molecules).

In a hypertonic solution (a highly concentrated solution), cells will shrivel
