The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.
selective permeability
Selective permeable
The cell wall in plants and the cell membrane in animals and bacteria.
The cell membrane controls what substances enter and leave the cell and at what rate it also separates the inside of the cell from its surroundings keeping the contense of the cell together and concentration gradients in place and don't forget it also contains receptors which allow messages to be convayed to cells.
