Question

How do cell wall permit the cell of the fungi to stand very dilute external and media?

Answer 1

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.
