The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells. 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.
The most important property of the cell membrane is its selective permeability: some substances can pass through it freely, but others cannot. Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.The selective permeability of the cell membrane allows a cell to maintain its internal composition at necessary levels.mall and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
