WebFeb 13, 2024 · Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability. What is the function of a selectively permeable membrane? The selectively-permeable cell membrane protects the cell. WebFeb 22, 2024 · Cells need a selectively permeable barrier sometimes called a semi-permeable membrane because some items need to be allowed to come in while others need to be let out of the cell. Cells could not be non-permeable which would mean nothing in and nothing out because the cells need to get nutrients and water in and get wastes out.
