Osmosis

• The cell has a lower concentration of a molecule in it

• The molecule is unable to diffuse across the membrane into the cell to increase the concentration

• Water can cross the membrane

• Water diffuses out of the cell to try to increase the concentration inside

• The cell loses its volume and shrinks
