Osmotic pressure - osmotic potential

Vedclass · Answer

(B) The osmotic pressure $(OP)$ of a solution is the pressure that must be applied to prevent the movement of water into the solution across a semi-permeable membrane.Osmotic potential $(\Psi_s)$ is the negative value of osmotic pressure, i.e., $\Psi_s = -OP$.Therefore, numerically, osmotic pressure and osmotic potential are equal, although they have opposite signs.In a flaccid cell, the turgor pressure $(TP)$ is zero, and the osmotic pressure equals the diffusion pressure deficit $(DPD)$.However, the most direct numerical similarity defined in plant physiology is between osmotic pressure and osmotic potential (ignoring the sign).Thus, option $B$ is the most accurate representation of numerical similarity.
