The 2-D model shows a plant cell that is placed in an isotonic solution. What do the arrows represent in the model?

The movement of solute and solvent molecules takes place in the same direction at the same time.

The movement of solvent molecules takes place at a faster rate into the cell than out of the cell.

There is equal movement of solvent molecules into and out of the cell, resulting in no net movement.

There is equal movement of solvent molecules into the cell and solute molecules out of the cell, resulting is no net movement
