Background Research Diffusion is the movement of molecules from an area of higher concentration to that of a lower concentration.

With the loss of this osmotic pressure the supportive structure of the plant is lost and the plant becomes limp and shriveled. By adding particles such as Na and Cl, the osmotic pressure within the cell decreases. The result of this decrease in osmotic pressure is the shrinking of the cell.
