Pressure potential Definition:
Pressure potential (Ψp) is the physical pressure on a solution.
Campbell Biology by J.B. Reece, L.A. Urry, M.L. Cain, S.A. Wasserman, P.V. Minorsky, R.B. Jackson
Pressure potential Notes:
Unlike Ψs, Ψp can be positive or negative relative to atmospheric pressure. For example, when a solution is being withdrawn by a syringe, it is under negative pressure; when it is being expelled from a syringe, it is under positive pressure. The water in living cells is usually under positive pressure due to the osmotic uptake of water.
