    In plant-water relationships, symbol \['{{\psi }_{W}}'\] is used to represent

    A)  Osmotic pressure           

    B)  Water potential

    C)  Solute potential

    D)  Osmosis

    Correct Answer: B

    Solution :

     Water potential is the potential energy of water per unit volume relative to pure water in ref-erence conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as surface tension. Water potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter
