It permits to enter different important ingredients and different types of salts to cytoplasm which is important to cell growth, function and metabolism but don't allow to transmit any unnecessary and harmful constituents such as unnecessary amino acid, not to use in protein synthesis then, different types of harmful drug which we take as medicine. So we can see it allow only selected item. That's why it is called as SelectivelyPermeable Membrane.
