Hey mate
Here is ur answer
Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is possible to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane.
Eg.If a living plant cell is immersed in a concentrated sugar solution, the concentration of water molecules inside the cell will be higher than outside. As a result, water will move by Osmosis from the higher water potential inside the cell to the lower water potential outside. The cell contents will shrink away from the cell wall and it will a plasmolysed

Answer:
when a living cells loses water through osmosis, there is shrinkage or contraction of the contents of cells away from the cell wall this is known as plasmolysis. example- shrinkage of vegetables in hypertonic conditions.
