Cell as a City




Peter Calfo and Ethan Callaghan

Cell
City

CELL

• The Cell is a city
• Has a fixed boundary
• Has many working substances just like a City has work places and a working society.

Cell Membrane
Border

CELL MEMBRANE

• Is like a border in a city just like the border of the cell
• Allows substances to come in and out, just like a border.
• Doesn't allow some substances into the cell.

Ribosome
Factories and workers

RIBOSOMES

• Ribosomes make the products of a cell just like factory workers create the products for a City and for the society.
• Creates the substances that allows the cell to run, just like the city needs products operate

Nucleus
City Hall

NUCLEUS

• The nucleus controls the cell, just like the city hall controls a City.
• The nucleus is the "brain" of the cell

Mitochondria
Power Plant

MITOCHONDRIA

• The mitochondria provides power for the cell, just like the power plant provides power for the city.
• The mitochondria is considered the power house of the cell
• Power plants create energy and power for the city

Nucleolus
Mayor

NUCLEOLUS

• Brings ribosomes and proteins together just like a mayor brings factory workers and the society together.
• Nucleolus is where the assembly of ribosomes begin.
• The mayor is in charge of creating jobs for workers and unity.

Cell Wall
Border Patrol

CELL WALL

• The cell wall controls what goes in and out of the cell, just like border patrol controls what enters the city.
• Cell wall is a supporting layer around the cell membrane

Smooth ER
Paved Highway

SMOOTH ER

• Smooth ER serves as a transportation in the cell
• Is a paved highway because it is not rough.

Rough ER
Rough highway/road

ROUGH ER

• Serves as a source of transportation, but is not smooth.
• Rough highway is like a rough ER because it transports "substances" to get from one place to another.

Golgi Apparatus
Post Office

GOLGI APPARATUS

• As proteins leave the rough ER, the Golgi Apparatus gives "address tags" to get the proteins to the right destination
• A post office gives letters and mails to the right destinations in the society.

Lysosomes
Garbage Dump

LYSOSOMES

• Lysosomes serve as a "clean up crew", because they break down lipids, carbohydrates, and proteins into smaller molecules.
• The dump burns and breaks down trash to make it more compact to eliminate waste.

Vesicles
Public Transport

VESICLES

• Stores, transport, and deliver proteins.
• Buses and public transports take people from place to place.

Central Vacuole
Warehouse

CENTRAL VACUOLE

• Store the cells materials such as water and enzymes
• Warehouses store products and objects that are in reserve for a later time.

Chloroplasts
Farm or farmer

CHLOROPLASTS

• Produces food for a cell
• Farmers watch over animals and produce products and food for the city and society.

Flagella
Cars

FLAGELLA

• Helps move the cell and substances on the cell
• Cars are a good way to transport people for one location to another.

Cytoskeleton
Construction Company

CYTOSKELETON

• Cytoskeleton provides structure, strength, and ability to the cell.
• Construction workers create and build everything in the city.
