Question

the cell membrane

the cell membrane surrounds the cell and regulates the movement of molecules in and out of the cell. it is only 8 nanometers thick, and it separates the living cell from its surrounding environment. the fluid surrounding the cell is called the extracellular fluid. it consists of nonliving components such as ions, proteins, sugars, and blood.

describe what the cell membrane does:

Identificar la función principal

Using the Cell Membrane Function knowledge point
La membrana celular rodea la célula y regula el paso de moléculas hacia adentro y hacia afuera de ella.

Identificar la función de separación

Using the Cell Membrane Function knowledge point
La membrana celular separa la célula viva de su entorno externo (el líquido extracelular).
</reasoning>

<answer>
La membrana celular realiza las siguientes funciones principales:

1. Rodea la célula y la separa físicamente de su entorno externo (el líquido extracelular).
2. Regula el movimiento de moléculas, controlando qué sustancias entran y salen de la célula.
