An example of cell membrane would be the border of a city, it's designed to protect everything inside
the barrier (city).
It also accepts helpful things to pass through it, for example food and supplies to help the city grow.
The residents and homes fill the city. The people and houses
represent the cytoplasm because the cytoplasm fills the cell
like our people fill the city.
The nucleus is the center of the cell, the brains of the
operation . The center of the city is the city hall,
that would be a good representation of the nucleus because
the hall also acts as the decision maker, all information/
activity goes through the nucleus/city hall.
The endoplasmic reticulum is an organelle that packages and
stores protein the feeds the cell.
In the city factories store and package our food items.
Ribosomes are small food producing organelles just like farms
that produce food for our city
These organelles functions are packaging,
labeling and delivering proteins inside and outside the cell.
Just like our mail delivery systems.
The mitochondria is the energy center of the cell.
The windmill farm is similar to this organelle because they both
These organelles store extra food or waste our city uses
ware houses to store extra goods just like a cell uses vacuoles.
