Since the cell membrane controls movement of materials in and out of the cell, I'd say the border police because they controls what comes in the country and out of the country.
The shell is most similar to the cell membrane because it covers and surrounds the egg and it protects it. It allows heat and other things to come in and out of it.

Dialysis tubing is often used to emulate the selective permeability of the cell membrane.
The balsam plant leaf cell consists of a nucleus, chloroplasts, vacuole (sap), cell wall and the cell membrane. An easy way to remember this: 1) Think of the hard boiled egg. Whenever you eat it, there's this hard skin you need to peel off. This represents the cell wall. 2) Then, there's this thin white layer. This represents the cell membrane. 3) And it goes on and on and on until the yolk represents the nucleus. Simple!
