Detailed explanation-1: -Being selectively permeable allows the cell to bring in molecules it needs and exclude molecules it does not. It also allows the cell to control when certain molecules move into or out of the cell. This allows for complex signaling cascades that regulate cell function.

Detailed explanation-2: -The selectively-permeable cell membrane protects the cell. It maintains the balance in the internal environment of the cell by transporting the toxic substances outside the cell and bringing the nutrients inside the cell.

Detailed explanation-3: -Answer and Explanation: The cellular plasma membrane, which encloses the cell, regulates the movement of substances in and out of the cell. The plasma membrane, being semi-permeable, permits the entry of certain substances, and restricts others.

Detailed explanation-4: -The ‘cell membrane’ (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.

Detailed explanation-5: -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.
