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)
looking at the cell, a city wall, as oposed to a city boundry.
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.
Animals do not have cell walls, animals cells with cell walls do not exist.
helo
No, there are no cell walls in animal cell.
They differ because fungus cell walls are made of chitin whereas plant's cell walls are made of cellulose
Plant cells have cell walls, animal cells don't have cell walls.
No animal has cell walls. Only plants and certain protists have cell walls.
Plants have cell walls, there are no animals with cell walls.
they protect the cell from damage. only plant calls have cell walls.
whats the cell walls job??
