The Cytoplasm is like the environment because everything is contained in it.

The cell membrane is like the boundaries of a city because it is the border of the cell and protects the cell.

Ribosomes are like a factory because they are part of assembling the proteins, like a factory assembles their products.

The nucleus is like the city hall because that is where the mayor is, who is in charge of everything else, just like how the nucleus is the control center of the cell.
