A good analogy for a nuclear membrane would be a bouncer, or doorman.
It could also be described as a shell, a filter, or a library desk...
What is an analogy of a nuclear membrane?
To pick a good analogy for a nuclear membrane, you'll first need to know exactly what the nuclear membrane does:
Its main task is to protect all the vital information located within the cell nucleus. Because different molecules and compounds need to travel in and out of the nucleus, the membrane is tasked with controlling what comes in, and what comes out.
This is similar to the role a doorman has in a nightclub. He's charged with making sure only the 'right' people make it inside (although a doorman wouldn't usually stop people from leaving a nightclub...).
The analogy of a 'filter' also works for much the same reason.
The nuclear membrane can also be described as the 'shell' of the nucleus, because it provides protection, but also a rigid structure to which other things are attached.
The library desk analogy takes a little bit more imagination, but is essentially a reference to the way the membrane controls what's 'checked in and out' of the nucleus.
