A Plant Cell Is Isolated and Placed in a Water

question 126

Multiple Choice

A plant cell is isolated and placed in a water bath.Due to dissolved solutes within the cell, the cell has a negative solute potential (_s = 1.3 MPa) .At the same time, placing the cell in the water bath creates a positive pressure potential within the cell (_p = 1.5 MPa) .Which of the following regarding the water potential within the cell (_cell) is true?

• A)  _cell is the product of the two values (i.e.,  =  1.95 MPa), and there is a net movement of water into the cell.
• B)  _cell is the product of the two values (i.e.,  =  1.95 MPa), and there is a net movement of water out of the cell.
• C)  _cell is the sum of the two values (i.e.,  = 0.2 MPa), and there is a net movement of water into the cell.
• D)  _cell is the sum of the two values (i.e.,  = 0.2 MPa), and there is a net movement of water out of the cell.
• E)  _cell is the difference of the two values (i.e.,  = 2.8 MPa), and there is a net movement of water out of the cell.
