Cell membranes are the protective, semi-permeable barriers that surround and define the boundaries of cells, playing a crucial role in maintaining cellular integrity and regulating the movement of substances in and out of the cell. Composed primarily of a double layer of phospholipids along with proteins, cholesterol, and carbohydrates, cell membranes are involved in a variety of cellular processes, including communication, transport, and signal transduction. They allow essential nutrients to enter the cell while expelling waste products and help in maintaining the proper environment for cellular function. The dynamic and selective nature of cell membranes is vital for the survival and proper functioning of all living organisms.
