Las paredes externas de una casa o un automóvil brindan una barrera fuerte e inflexible que protege a sus habitantes humanos de un mundo externo rudo e impredecible. Podría esperarse que el límite externo de una célula viva estuviera construido de una barrera igual de fuerte e impenetrable porque también debe proteger su delicado contenido interno ante un ambiente no vivo y a menudo inhospitalario. Sin embargo, las células están separadas del mundo externo por una estructura delgada y frágil llamada membrana plasmática que sólo mide 5 a 10 nm de espesor. Se requerirían casi 5 000 membranas plasmáticas apiladas una sobre otra para igualar el grosor de una sola página de este libro.
