A sucrose solution in a beaker has a solute potential of -4 bars.  A cell with a solute potential of -2 bars is placed in the beaker.  What will be the direction for the net movement of water?

• into the cell
• out of the cell
• there will be no net movement

• (B) Glucose will enter the “cell.”

• (C) Pinocytosis will occur.

• (D) There would be a net movement of water into the “cell.”

• (E) There would be no net movement of water.
