Cell City Analogy
What to Do: Read the Following Two Paragraphs on Grant City. Each of the underlined
parts of the city represent a part of a cell. Match the Underlined Parts of the City to the
parts of the cell below,
In a far away city called Grant City, the main export and
production product is the steel widget. Everyone in the town
has something to do with steel widget making and the entire
town is designed to build and export widgets. The town
hall has the instructions for widget making, widgets come in
all shapes and sizes and any citizen of Grant can get the
instructions and begin making their own widgets. Widgets are generally produced
in small shops around the city.
After the widget is constructed, they are placed on special carts which can deliver
the widget anywhere in the city. In order for a widget to be exported, the carts
take the widget to the postal office, where the widgets are packaged and labeled
for export. Sometimes widgets don't turn out right, and the "rejects" are sent to
the scrap yard where they are broken down for parts or destroyed altogether. The
town powers the widget shops and carts from a hydraulic dam that is in the city.
The entire city is enclosed by a large wooden fence, only the postal trucks (and
citizens with proper passports) are allowed outside the city.
Match the parts of the city (underlined) with the parts of the cell.

What to Do: Using pencil crayons colour a typical prokaryote cell according to the text
below.
Bacteria have a very simple cell design. Most
of them have a thick outer covering called
the cell wall.
1. Color the cell wall purple (it’s the
outermost layer).
2. Just within the cell wall is the cell
membrane. Color the cell membrane pink.
3. Along the surface of the bacteria cell, you
might encounter structures called pilus,
whose job is to help the bacteria stick to
surfaces. Color all the pilus light green.
4. Bacteria might also need to move around
in their environment, so they can have
structures called flagella, which resemble
tails. Find the two flagella pictured and color
them dark green.
5. The watery interior of the cell is
called cytoplasm, and it has the texture of
jello. Color the cytoplasm light blue.
6. Sprinkled throughout the cell are small
roundish structures called ribosomes.
Ribosomes make proteins for the cell. Color
all of the ribosomes red.
7. Every prokaryote cell has DNA floating within the cytoplasm, which usually looks like
a twisted strand of spaghetti. DNA contains the instructions for the cell, basically it is
the control center. Find the DNA and color it yellow.
