Why is cell membrane called a selectively permeable membrane?

WebIntroduction This factor influences how easy it is for something to pass through the membrane. A cell surface membrane is made up of phospholipids, arranged tail to tail in a structure called a phospholipid bilayer. They are selectively permeable, meaning they only allow the passage of certain molecules such as lipid-soluble, small and uncharged.
