<prompt> Hlalosa sepheo sa lera la selenan  <response>: Instruction in English: Describe the purpose of the cell membrane . Response in English: The cell membrane, also known as the plasma membrane, is a protective barrier that surrounds the cell, separating its internal environment from the outside world. Its primary function is to regulate the movement of substances in and out of the cell, allowing the influx of necessary nutrients, such as oxygen and glucose, and the removal of waste products. It also acts as a selective barrier, preventing the entry of harmful substances into the cell, and maintaining the proper balance of ions and molecules. The cell membrane is also involved in cell signaling, cell adhesion, and maintaining the cells shape and structure. Overall, the cell membrane plays an essential role in maintaining the proper function and health of the cell. .
