Answer:

The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. If plasma membrane ruptures or breaks down then molecules of some substances will freely move in and out of the cells.

[ OR]

The cell membrane or plasma membrane is a biological membrane that separates the interior of the cell from the outside environment. The plasma membrane is called as selectively permeable membrane because it regulates the movement of substances in and out of the cell. It means that the plasma membrane allows some material to pass through it while at the same time it blocks other material from entering through it.
