Question

what is plasma membrane

Answer 1

The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space).[1][2] It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules

Answer 2

Answer:

The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell's contents and the outside of the cell.
