Water Potential (ψ)Can Be Thought of as the Tendency for Water

question 22

Multiple Choice

Water potential (ψ) can be thought of as the tendency for water to move from one place to another.In plants,it is made up mainly of solute potential and pressure potential.Hypothetical plant cells A and B are adjacent to each other.The solute potential (ψS) of cell A is -0.35 MPa,and its pressure potential (ψP) is +0.15 MPa.The solute potential (ψS) of cell B is -0.30 MPa,and its pressure potential (ψP) is +0.05 MPa.In which direction will net water movement occur?

• A)Neither;cells A and B are in equilibrium with each other.
• B)from cell A to cell B
• C)from cell B to cell A
