Cell Analogy?

Question

For my analogy, am I comparing the parts of a cell to a school. What would the cell membrane be? Thanks!

Answer 1

If it's an animal cell, you could use the exterior wall of the school because:
-- that's the outside covering
-- it determines what can enter and leave the school (doors, windows, locks, ...)

If it's a plant cell, you might have a problem. The walls of the school still should be the plasma membrane for the reason that it does determine what enters and leaves. However, the cell wall has to be on the outside of that.

Maybe you have a brick school, and the layer of brick on the very outside can be the cell wall. The inside of the outer wall can be the membrane.

Answer 2

The cell membrane would be the teacher or principal meeting you at the door of the building. The cell membrane is not rigid like the actual building or door would be, but it is semi-permeable.

Answer 3

on an identical time as i'm often a pessimist, i think of at last those suggestions will exchange into difficulty-loose information. i think of maximum persons understand the Earth is going around the solar, even although in Galileo's time the Church renounced it. and a few Christians i understand are completely sensible, and don't take the Bible as a technology instruction manual. regrettably, far too many human beings do. -Atheist
