When a cell reaches equilibrium (with water) it creates osmosis pressure. Osmosis pressure is when the hydrostatic pressure from inside the cell is greater then the pressure from outside the cell. Organic solvents also affect the permeability of the cell. Ethanol is miscible with water and both posses hydrogen bonds.
