An Animal Cell is like a City

By Cici Sheeks

An animal cell is like a city, because each part works together to create a great system.

The cell membrane is like the city limits, because they control what comes in and out of the city.

The cytoplasm can be compared to the landscapes and general roads within a city, where everything takes place.

The mitochondria is like the power plant of the city, which supplies the city with energy and power.

The endoplasmic reticulum is like a road or highway system, which transports materials to where they are needed throughout the city.

Ribosomes are similar to industrial buildings, and factories which produce new building materials (like proteins) to make structures in the city more efficient and replace those who are damaged.

The nucleus has some of the same qualities as a city hall, which controls the functions of the city.

The Golgi Apparatus is like the post office of the city, which packages materials (proteins) and sends them throughout the city.

The lysosomes are like the city dump, which contains and breaks down unwanted waste and broken buildings.

Peroxisomes are like sewage treatment plants, which break down dangerous toxins within the city.
