something to represent a cell membrane would be a sponge because it lets things pass in and out of it
It can be compared to a gate because it surruonds the building.(we are using a building for our cell!)
A cell membrane is made out of a double-layer of phosphilipids.
In Prokaryotic cells, membrane controls what enters and leaves the cell, they also give the cell a shape and keep organells together.
The cell membrane controls movement of materials in and out of the cell.

It is a soft object
Vacuoles
A cell membrane is similar to the object you use as a balloon. It forms the wall around the cell and allows some things to come in and some to go out. It is a boundary.
Vesicles
Both animal and plant cells have cytoplasm.
