Explanation:

The cell are placed in isotonic, hypotonic and hypertonic solutions respectively. Cells in isotonic remain the same since there is no net flow of water in any direction. Cells in hypotonic solution will take in water by osmosis, swell and burst. The osmotic pressure of the external solution is lower than that of the cell. This is called haemolysis. Cells placed in hypertonic solution will lose water by osmosis, shrink and the cell membrane becomes wrinkled.The osmotic pressure of the external solution is higher than that of the cell. This is known as laking or crenation.
