The cell membrane (plasma membrane) is describe as a highly selective barrier composed of a lipid bi-layer. This structure plays an important role in moving molecules across the cell membrane in order for the cell to maintain homeostasis. If the cell is unable to take in the materials it needs or remove what it does not need, the cell may die.
