Answer:
Hypotonic solution.
Explanation:
Osmosis is the movement of the solute particles towards the region of lower concentration from the region of the higher concentration through the semi permeable membrane. Some molecules enter in the cell through the process of osmosis.
Three types of osmosis solution are hypotonic solution, hypertonic solution and isotonic solution. The hypotonic solution may be defined as the solution in which the solute has low concentration than the solution and has low osmotic pressure. The water enters into the cell from the solution causes swelling and lysis of the cell.
Thus, the answer is hypotonic solution.
