Detailed explanation-1: -The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings.
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: -Plasma membrane controls the flow of substances in and out of cell.
Detailed explanation-5: -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.
