It also prevents movement of s â¦ ome other materials, therefore the plasma membrane is called a selectively permeable membrane. 104 people found this useful. Johnellishartford.
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. Active transport processes require the cell to expend energy to move the materials, while passive transport can be done without using cellular energy.
