Answer

  1. The solution in which the concentration of solutes is more and the concentration of solvent (water) is less as compared to the cytoplasm of a specific cell.

Explanation:

In the hypertonic solution, the concentration of solutes is more and the concentration of solvent (water) is less as compared to the cytoplasm of a specific cell.

If a cell is placed in such a solution plasmolysis will occur due to the movement of water from the cell to the outer environment.
