Plant cell have a rigid outer covering called the cell wall. The cell wall lies outside the plasma membrane. The plant cell wall is mainly composed of cellulose. It is permeable and is dead layer. Its main function is to provide the plant mechanical strength and shape. Cell walls permit the cell of plant, fungi and bacteria to withstand very dilute external media without bursting. The cell swells building up pressure against the cell wall. The wall exerts an equal pressure against the swollen cell.

Because of their walls, such cells can withstand much greater changes in the surrounding medium than animal cells.

Answer:

Fungi withstand very dilute/hypotonic external media without bursting because of their cell walls.

In such media cells swells up by taking water through osmosis, building up pressure against the cell wall.

The wall exerts an equal pressure against the swollen cell, thus preventing it from bursting.
