Dear Mr. Plumbob,
We are pleased to inform you that we have chosen your architectural firm
to design our Megalopolis factory. As you know, I have always been fascinated by
the biology of cells. Therefore, I have decided to model my factory after an animal cell.
Your job is to design each part of the factory so that it represents a cellular
structure. I have faith in your firm’s ability to complete this project.
Sincerely,
M. A. Richmann

1. Each cell component will be represented by a factory component. In the right column of the chart below, describe
the function performed by each pair of components. The
first one has been done for you.

2. How might the architectural plans and blueprints for the
construction of the Megalopolis factory be compared to
the DNA in cells?

3. Would there be any advantages to having a factory that
functioned more like a plant cell than an animal cell?
Explain.

4. In your ScienceLog or on graph paper, design and label a
diagram for the Megalopolis factory. Include all the components listed in the chart on page 33. Label each factory
component with its cellular counterpart.

Making Comparisons
2. How might the architectural plans and blueprints for the
construction of the Megalopolis factory be compared to
the DNA in cells?
Sample answer: Both the architectural plans and DNA contain
all the information needed for construction. By examining
blueprints and DNA, one can learn how materials flow
through the factory and through the cell, respectively.
3. Would there be any advantages to having a factory that
functioned more like a plant cell than an animal cell?
Explain.
Sample answer: Plant cells have a rigid cell wall for protection; a factory with a strong barrier would be more secure.
would be useful to have storage facilities in the factory. Plant
cells use chloroplasts to make food from the sun’s energy;
a factory that could produce its own fuel would be more
self-sufficient than one that required fuel from the outside.
Answer to item 4:
Answers will vary.
Students should include
and label all components
listed in the chart on
page 33. Look for a logical placement of the
components.
