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!
Both Systems Make A Final Product
Cells
Keebler Factory
 Our factory can make a
variety of cookies.
 Our cells can make a
variety of proteins.

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.
Factories Need a Boss
Keebler Factory
Cell
Ernie Elf
 He controls everything that
happens inside the factory.
Nucleus
 It controls everything that
happens inside the cell.
Ma Keebler
 Inside Ernie’s office, trains elf
workers.
Nucleolus
 inside nucleus, makes ribosome
workers.

Factories Need Instructions
Keebler Factory
Recipes
 The instructions for making
delicious cookies.
Cell
DNA (chromatin)
 The instructions for making
important proteins.
Factories Need Workers
Keebler Factory
Elves
 They read the recipes and make
cookies.
 They work along the assembly
line or on the factory floor.
Cell
Ribosomes
 They read the DNA and make
proteins.
 Found on ER or floating in
cytoplasm.
Factories Need To Move Their Product
Keebler Factory
Cookie Assembly Line
 A large conveyor belt that
moves cookies to their next
location.
Cell
Endoplasmic Reticulum (ER)
 A maze of membranes that
moves proteins to their next
location.
Factories Need to Pack & Ship
Keebler Factory
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.
Cell
Golgi Body
 It packages, tags, and ships the
proteins out of the cell or to
storage.
Factories Need Vehicles
Keebler Factory
Keebler Factory Cars
 These carry the cookies from
one part of the factory to the
other.
Cell
Vesicles
 Carries the proteins from one
part of the cell to the other.
(sounds like “vehicle”)
Factories Need Storage
Keebler Factory
Cookie Warehouse
 Cookies can be stored in this
room along with other raw
materials until needed.
Cell
Vacuole
 Stores proteins along with food
and water until needed.
Group Activity! – Map the Path of our Product
Keebler Factory
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.
Cell
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?
Factories Need Protection
Keebler Factory
Cell
Factory Door
 It regulates what can enter and
exit the factory.
Cell Membrane
 It regulates what can enter and
exit the cell.
Factories Need Space
Keebler Factory
Factory Floor
 It holds all the other parts of
the factory in place.
Cell
Cytoplasm
 It holds all the other cell parts
in place. It’s like Jell-O.
Factories Need Power
Keebler Factory
Generators
 They create energy so that the
factory can power its baking
machines.
Cell
Mitochondria
 These “mighty” organelles
break down glucose (sugar) to
create energy which powers the
cell.
Factories Need to Stay Clean
Keebler Factory
Clean-Up Crew
 They clean the factory by
removing waste, dirt, and
debris from the factory floor.
Cell
Lysosomes
 They clean the cell using
powerful chemicals to digest
waste, old cell parts, and
foreign invaders.
Plant Cells Have a Few More Parts
Keebler Factory
 What could this be in our
Keebler factory?
 Bark on hollow tree bakery
 Leaves on hollow tree bakery
 Water Cooler inside break
room
Plant 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.
