Osmosis can be measured by osmotic strength, concentration or pressure.
Concentration gradient: The concentration gradient affects the rate of osmosis. The faster osmosis takes place in a solvent, the lower the solute concentration in that solvent must be. Darkness and light are other osmosis-related elements; the more light there is, the more quickly osmosis occurs.
Osmosisisis is determined by concentration of the solute . Water diffuses into the area of higher concentrations from the area of lower concentrations.
