Detailed explanation-1: -You have a cell, with a semi permeable membrane and a 1.5% potassium concentration. You put it into a solution of 2% potassium. What do you expect to see happen to the cell? The cell will shrink.

Detailed explanation-2: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.

Detailed explanation-3: -An animal cell has a 2% percent salt concentration. It is placed into a solution with a 0.05% salt concentration. Water will move out of the animal cell, causing it to shrivel.

Detailed explanation-4: -If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

Detailed explanation-5: -If two solutions of different concentration are separated by a semipermeable membrane, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution. This process is called osmosis. At the cellular level, both processes are types of passive transport.
