How can a cell be compared to a city?

Answer 1

I personally don't think that the comparison is that close, however, if we want to we could say that the cell nucleus functions as City Hall, the endoplasmic reticulum serves a similar function to city streets, mitochondria are a kind of power plant, cell membranes are comparable to a city wall (although in the 21st century, very few cities still have walls) and all the organelles of the cell work together in much the same way that the happy and responsible citizens of a community work together for their common good.
