Summary Introduction
Introduction: All cells have a cell membrane that is also known as plasma membrane, and it is made up of proteins and lipids. It provides cell shape and structural support. It is a semi-permeable membrane that regulates the entry as well as the amount of substances entering in the cell. They play the role of gatekeeping.
