Based on the information in the graph, explain what physical process causes the cell to change size.

Osmosis

Explanation:

Osmosis is the process in which solvent molecules move from lower to higher  concentration through a semipermeable membrane.

When a cell is placed in a hypertonic solution, the  cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.

Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.

Hence, the correct answer is osmosis.
