An Animal Cell is Like a City

By: Ashleigh Erickson, Hour 7

Cell Membrane

The cell membrane is similar to to the city border patrol of a high-security city. These officers control what goes in and out of their city.


The cytoplasm in cells can be compared to the people in a city, because the people are what fill up the city, just as cytoplasm fills up a cell.


Just like a city's town hall and government, the nucleus holds all of the information about the cell needed to keep it up and running.


Power plants supply power energy to the entire city, and mitochondria do the same for cells.

Endoplasmic Reticulum

The endoplasmic reticulum is like a city's highway system because it transports proteins all over the cell, just like how highway systems help to transport people and products all across the city.


Ribosomes are like construction workers in a city because they build proteins, just as construction workers build buildings and houses in a city.

Golgi Apparatus

The golgi apparatus is like the post office of a city because it packages proteins, just like a post office packages and ships mail.


Lysosomes are like a city's landfill, because this is where waste goes to get disposed of, and lysosomes digest the cell's food and waste.


Peroxisomes are like sanitation workers because they digest and break down waste and toxins, such as alcohol, and sanitation workers help to get rid of waste in the city.


Flagella and cilia are like vehicles in a city because they help with movement in the cell, just like vehicles move people and things around in the city,


Centrioles are like building onto a city because they help with cell division, and therefore add onto the amount of cells, just as  building and construction adds onto the size of the city.
