in what conditions water potential of pure water cant be more than zero
Answers
Solute Potential. Solute potential (Ψs), also called osmotic potential, is negative in a plant cell and zero in distilled water. Typical values for cell cytoplasm are –0.5 to –1.0 MPa. Solutes reduce water potential (resulting in a negative Ψw) by consuming some of the potential energy available in the water.
Potential of pure water can’t be more than zero when we dissolve solute in the water.
Explanation:
The water potential is depicted as a sum of solute potential and pressure potential. When a solute is dissolved in the water, potential of pure water decreases and it leads to the negative water potential value.
On the other hand, the water potential of pure water increases when the pressure more than atmospheric pressure is applied to water.
