A Cell Has a Pressure Potential (_p) of +1

question 155

Multiple Choice

A cell has a pressure potential (_p) of +1.5 MPa and a solute potential (_s) of +1.5 MPa.What does this mean for the resulting value of  and the flow of water, provided the cell is in a bath of pure water ?

• A)  = 3 MPa; Water will flow into the cell.
• B)  = 3 MPa; Water will flow out of the cell.
• C)  = 0 MPa; Water will flow into the cell.
• D)  = 0 MPa; There will be no net movement of water.
• E)  = 2.25 MPa; Water will flow out of the cell.
