Scientific definitions for cell membrane cell membrane. The thin membrane that forms the outer surface of the protoplasm of a cell and regulates the passage of materials in and out of the cell. It is made up of proteins and lipids and often contains molecular receptors.Click to see full answer. Keeping this in consideration, what is a cell membrane easy definition?The cell membrane is a thin flexible layer around the cells of all living things. It is sometimes called the plasma membrane or cytoplasmic membrane. Its basic job is to separate the inside of cells from the outside. In all cells, the cell membrane separates the cytoplasm inside the cell from its surroundings.Likewise, what is the cell membrane and its function? The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit. Besides, what is in a cell membrane? Cell membrane. Enclosed by this cell membrane (also known as the plasma membrane) are the cell’s constituents, often large, water-soluble, highly charged molecules such as proteins, nucleic acids, carbohydrates, and substances involved in cellular metabolism.Why is the cell membrane so important?All living cells contain a cell membrane, the semipermeable structure that surrounds the cell. This flexible ability is important because it allows the cell to survive in differing environments, such as when immersed in water over long periods of time.
