The Cell Wall would be the wall surrounding the city (no equivalent in modern cities). In comparison, the membrane would be the city border patrol. Nobody is going to get past the cell wall, but once they do whether or not they enter the cell (city) is determined by the membrane and its proteins (border patrol)
The city analogy for a nuclear membrane is like a security wall around a city. Just as a security wall protects the city by controlling what enters and exits, the nuclear membrane surrounds the nucleus of a cell and regulates the passage of molecules in and out of the nucleus to maintain cellular function and integrity.
While cell membranes might be around every cell, cell walls made of cellulose are only found around plant cells. There are other sorts of cell walls. Many but not all bacteria also have a structure called a cell wall.Fungi and some protozoa also have cell walls. These walls are made of proteins. They serve the same purpose of protecting and maintaining structure.
to allow the plant to stand upright
A door is an example of a cell wall. It is a protective wall, provides, and maintains the shape of these cells. They also serve as a protective barrier.

It protected the city from invaders.
What purpose did the wall around a city serve? a. to protect inhabitants of the city-state from attack b. to collect water that could be used to irrigate farmland c. to protect inhabitants of the city-state from floods d. to keep people from moving to another city-state
I think it wasn’t used as a defense mechanism to protect city-state from being attacked. - to protect inhabitants of the city-state from attack.Tell me if I’m wrong :)
The wall was around the city itself, not the agricultural land as well. In the event of invasion the people could retire inside the walls and defend them.
Yes, yes it did.
They did man they had a NATURAL WALL

The wall in "Mending Wall" represents barriers and divisions between people. The purpose of the wall is to maintain boundaries and keep neighbors separate, while also serving as a metaphor for the challenges in human relationships and communication.
They both built a wall around the entire city
