Vedclass · Answer

(A) The experiment demonstrates the concept of osmotic pressure and osmotic potential. Osmotic pressure is the pressure required to prevent the movement of water into a solution through a semi-permeable membrane. Osmotic potential $(\Psi_s)$ is always negative, while osmotic pressure is the positive value of osmotic potential. Therefore, osmotic pressure is numerically equal to osmotic potential but with an opposite sign. Thus, option $A$ is correct.
