Plant cells have a cell wall to stop the cell from bursting, animals cells do not have a cell wall therefore they burst

Plant cells have a cell wall and a cell membrane. When water enters the cell it will swell up, the cell wall of the cell will stretch more and more and push back with hydrostatic pressure. This will raise the water potential inside the cell and eventually make the water potential inside and outside the cell equal. This will stop any more water entering because osmosis is the movement of water from higher to lower water potential.

Animal cells have a cell membrane and not a cell wall so if a cell is placed into pure water - water would keep entering untill it bursts causing a lysis. Animal cell must always be kept in a solution which has the same water potential as its cytoplasm or else it will not work.
