(a) When a pressure greater than atmospheric pressure is applied to pure water or a solution, its water potential is increased. It is equivalent to pumping water from one place to another.
(b) When water enters a plant cell due to diffusion, the cell becomes turgid. It increases the pressure potential. The pressure potential is mostly positive (vpp). Water potential is influenced by solute and pressure potential.
