Explanation:
Detailed explanation-1: -When a cell is kept in a hypotonic medium, the cells take up water from external medium and swell up. In plant cells, the cell membrane creates a pressure against the cell wall, which exerts an equal pressure against the swollen cell but do not burst.
Detailed explanation-2: -The cell wall provides mechanical support to the plant cell. When a plant cell is kept in a hypotonic solution, water enters the cell but it does not burst because of the pressure applied by the cell wall. Since it is rigid, it does not allow the cell to expand to an extent that it would burst.
