Vedclass · Answer

(D) The water potential $(\Psi_w)$ of a solution is defined as the difference between the chemical potential of water in a system and that of pure water at the same temperature and pressure.Historically, the term $DPD$ (Diffusion Pressure Deficit) was used to describe the water-absorbing capacity of a cell.According to the relationship: $\Psi_w = -	ext{DPD}$.Therefore, in terms of magnitude, the water potential of a cell is equivalent to the negative value of its $DPD$ (also known as Suction Pressure).Among the given options, $DPD$ is the concept most directly related to the historical definition of water potential in plant physiology.
