Explain how cell walls permit the cells of fungi to withstand very dilute external media without bursting.
(N/A) Fungi can withstand very dilute (hypotonic) external media without bursting due to the presence of rigid cell walls. When placed in a hypotonic solution,water enters the fungal cells through osmosis,causing them to swell. As the cell expands,it exerts turgor pressure against the cell wall. The cell wall,being rigid and strong,exerts an equal and opposite wall pressure,which prevents the cell from bursting.
