3. if a plant cell was placed in a solution which was hypotonic to the salinity of the cell itself, what would be the expected reaction? a. water enters the cell c. water released from central vacuole b. water exits the cell d. cell becomes less rigid

Water will exit the cell!

Explanation:

Because the solution is HYPOtonic, meaning the outside of the solution has a lower concentration of molecules (be it water, sugar, etc), the water within in the cell will leave in order to even out of the concentrations within and outside the cell.

"a.) well–developed vascular system."
