The Home as a Model for the Cell
Floating around in the cytoplasm are small structures called organelles. Like the organs in your body,
each one carries out a certain function necessary for the cell to survive. Imagine the cell as a home. The
organelles might represent people, places or parts of the home. Below are the descriptions of important
parts of your model home.

Garden – where the food is grown
Kitchen – where food is prepared
Pantry – where food is stored
Children – move items around the home
Composter – where wastes are disposed or recycled
Heater – where energy is produced to heat the house
Security system – to allow people in and out.
Floor – Holds all the structures
Parent/Guardian – makes sure the home is working properly
Fence – Gives added support to the house and yard
Solar panel on roof – collects sunlight for the home’s energy use
As you move through the worksheet, see if you can match the important parts of the home listed above
to the organelles in the cells. Write is complete sentences.
1. The nucleus is a large structure in the cell. It is the control center for all the activities in the cell.
a. What part of the home or person in the home represents the nucleus?
b. Why do you think so?
2. The cell membrane is a thin, covering that surrounds the cell. It controls what goes into and out
of the cell.
a. What part of the home or person in the home represents the cell membrane?
b. Why do you think so?
3. The endoplasmic reticulum is tube-like passages that transport proteins to the rest of the cell.
a. What part of the home or person in the home represents the endoplasmic reticulum?
b. Why do you think so?
4. The ribosomes are small round structures that make proteins.
a. What part of the home or person in the home represents the ribosomes?
b. Why do you think so?
5. The jelly-like area between the nucleus and the cell membrane is called the cytoplasm. It holds
the organelles.
a. What part of the home or person in the home represents the cytoplasm?
b.Why do you think so?
6. The mitochondria are small bean-shaped structures with a folded inner membrane. They provide
energy for the cell by change sugars into energy.
a. What part of the home or person in the home represents the mitochondria?
b. Why do you think so?
7. The lysosomes are small round structures. They contain digestive enzymes that break down
substances to be recycled or removed.
a. What part of the home or person in the home represents the lysosomes?
b. Why do you think so?
8. The vacuole is a sac that stores water, food, wastes or other materials for the cell.
a. What part of the home or person in the home represents the vacuole?
b. Why do you think so?
9. The Golgi body is a structure that packages and prepares proteins for the cell.
a. What part of the home or person in the home represents the Golgi body?
b. Why do you think so?
10. The Chloroplast is a green structure that converts sunlight, water and carbon dioxide into energy
for the cell.
a. What part of the home or person in the home represents the chloroplast?
b. Why do you think so?
11. The Cell Wall is a structure that is the outer boundary of the home. It provides added protection and
support.
a. What part of the home or person in the home represents the cell wall?
b. Why do you think so?
12. Why does this model of a home represent a plant cell?
11. To make this home represent a animal cell, what rooms, structures or people would have to be
missing from the home?
Part I: Home
On a plain piece of paper, you will sketch, color, and label a home. Each part of the home will be
labeled with its name and the name of the cell organelle that has a similar function.
