Why is the plasma membrane called a selectively permeable membrane: Why is the plasma

Why is the plasma ... The plasma membrane is called a selectively permeable membrane because it relatively allows the movement of substances from the inside of the cell to the outside and vice-versa. This selectivity depends on the requirements of the cell and the substances present in the surroundings of the cell. The plasma membrane is called a selectively permeable membrane because it allows only certain molecules or ions to pass through it by means of active or passive transport. Conclusion: Therefore, the plasma membrane is called a selectively permeable membrane because it selectively allows certain molecules to enter or exit the cell while blocking others, thus regulating the internal environment of the cell. ---
