Answer 1

Definition of Selectively Permeable Membranes

All cells are enclosed with a cell membrane. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport

Cell membranes are also called selectively permeable membranes, because they are selective in allowing entry of particles into the cell. This property of selective permeability is important because it ensures the survival of the cell.
