Define the term water potential.

Text Solution

Verified by Experts

Water potential is the measure of the relative tendency of water to move from one area to another it is represented by the sign `psi_(omega)` . The value of water potential of pure water at normal temperature and pressure is zero `(psi_(omega = 0))`, which is the maximum. This value decrease by the addition of solutes . Therefore the value of water potential in solution is less then zero or it is in negative
