text: the protoplasmic boundary of all cells that controls permeability and may serve other functions through surface specializations, for example, active ion transport absorption by formation of pinocytotic vesicles or receptor-mediated antigen recognition; its fine structure is trilaminar and consists of the electron-dense lamina externa and lamina interna with an electron-lucent lamina intermedia.
