SOLUTION
The plasma membrane, also known as the cell membrane or cytoplasmic membrane, is a thin layer that surrounds the cytoplasm of a cell and acts as a barrier, separating the internal environment of the cell from the outside world. It is composed of a lipid bilayer, made up of two layers of phospholipid molecules, with their hydrophobic (water-fearing) tails facing inward and their hydrophilic (water-loving) heads facing outward. This structure helps maintain the integrity of the cell and regulate the exchange of materials between the cell and its surroundings.
The plasma membrane is also studded with a variety of proteins, including channels, pumps, and transporters, which help regulate the movement of ions, molecules, and other substances in and out of the cell. The plasma membrane is a vital part of the cell, playing crucial roles in many cellular processes, including maintaining cell shape and providing structural support, signaling between cells, and regulating the flow of materials in and out of the cell.
