The Cell as a Keebler Factory
Cells are Living Systems
Welcome to the World of Cells! Introduction to Cells (2:55) Frank Gregorio
Cells are tiny systems that make up all living things, including YOU!
Tiny parts called organelles work together in this system to make proteins. This is a cell’s main job!
Proteins are important products that give you observable traits like hair, eye, and skin color.
We can compare our cell system to an everyday system we are familiar with: a Keebler Cookie Factory. You will be surprised at how similar the two really are!
Keebler Factory Cells
Our factory can make a variety of cookies.
Our cells can make a variety of proteins.
Both Systems Make A Final Product

PRE-THINK! Predict the function of each cell part by using what you know about the Keebler Factory parts. Write small notations in the labeled column.
Keebler Factory Cell
Ernie Elf He controls everything that
happens inside the factory.
Ma Keebler Inside Ernie’s office, trains
elf workers.
Nucleus It controls everything that
happens inside the cell.
Nucleolus inside nucleus, makes
ribosome workers.
Factories Need a Boss

Recipes The instructions for
making delicious cookies.
DNA (chromatin) The instructions for
making important proteins.
Factories Need Instructions
Keebler Factory
Elves They read the recipes and
make cookies. They work along the
assembly line or on the factory floor.
Ribosomes They read the DNA and
make proteins. Found on ER or floating in
cytoplasm.
Factories Need Workers
Cell
Cookie Assembly Line A large conveyor belt that
moves cookies to their next location.
Endoplasmic Reticulum (ER)
A maze of membranes that moves proteins to their next location.
Factories Need To Move Their Product
Keebler Factory Cell
Packing/Shipping Department
Fast Eddie packs the cookies into boxes, tags them with a tracking label, and ships them to stores to be sold or in warehouse storage.
Golgi Body It packages, tags, and
ships the proteins out of the cell or to storage.
Factories Need to Pack & Ship
Keebler Factory Cell
Keebler Factory Cars These carry the cookies
from one part of the factory to the other.
Vesicles Carries the proteins from
one part of the cell to the other. (sounds like “vehicle”)
Factories Need Vehicles
Keebler Factory Cell
Cookie Warehouse Cookies can be stored in this
room along with other raw materials until needed.
Vacuole Stores proteins along with
food and water until needed.
Factories Need Storage
Keebler Factory Cell
1. Take the six picture cards provided by your teacher and place them in the correct order to show the path a cookie takes through the Keebler factory.
2. Now create a caption for each card using six post-it notes. Stick the post-it next to the card.
3. Do the same process for the cell using the six picture cards and six NEW post-it notes.

THINK! – If you remove one of the pictures in our chain, is the cell still alive? Why or why not?
Factory Door It regulates what can enter
and exit the factory.
Cell Membrane It regulates what can enter
and exit the cell.
Factories Need Protection
Keebler Factory Cell
Factory Floor It holds all the other parts
of the factory in place.
Cytoplasm It holds all the other cell
parts in place. It’s like Jell-O.
Factories Need Space
Keebler Factory Cell
Generators They create energy so that
the factory can power its baking machines.
Mitochondria These “mighty” organelles
break down glucose (sugar) to create energy which powers the cell.
Factories Need Power
Keebler Factory Cell
Clean-Up Crew They clean the factory by
removing waste, dirt, and debris from the factory floor.
Lysosomes They clean the cell using
powerful chemicals to digest waste, old cell parts, and foreign invaders.
Factories Need to Stay Clean
Keebler Factory Cell
Cell Wall A rigid outer covering for
strength and support
Chloroplast A green organelle that
captures sunlight and turns it into food (glucose) for the plant
Large Vacuole Plant cells only have 1 large
vacuole filled with water

Visualization – The Inner Life of a Cell is Spectacular!
Now that you know a cell’s job is to make proteins, watch these proteins in action as they work to make the inner life of a cell come alive.
Harvard University selected XVIVO to develop an animation that would take their biology students on a journey through the microscopic world of cells.
