Question:
Define water potential and solute potential.
Solution:
Water potential (Ψw) is the sum of solute potential (Ψs) and pressure potential (Ψp): Ψw= Ψs+ Ψp.
The solute potential is also known as osmotic potential is the potential of solution that allows the water to enter the solution by diffusion or osmosis due to the presence of the solute in it.
