Detailed explanation-1: -Plasma membrane controls the flow of substances in and out of cell.
Detailed explanation-2: -The cell membrane regulates the transport of materials entering and exiting the cell.
Detailed explanation-3: -Specialized proteins in the cell membrane regulate the concentration of specific molecules inside the cell. Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage.
Detailed explanation-4: -Many cellular functions, including the uptake and conversion of nutrients, synthesis of new molecules, production of energy, and regulation of metabolic sequences, take place in the membranous organelles.
Detailed explanation-5: -It protects the cell from a variety of external stresses and chemicals. The phospholipid bilayer is made up of proteins, lipids, carbohydrates, and other substances. The plasma membrane’s different components make it a selectively permeable barrier.
