This is the powerpoint presentation my son completed for a cell analogy school project. Classmates help play act the organelles and doughnuts were provided to all as yummy "proteins."

1. A Cell is Like a Krispy Kreme
Doughnut Shop

2. No Pictures
• I recorded my voice to narrate my slides.
• I will be asking volunteers to act out the jobs
of the different organelles in my analogy.
• I did my project this way because I do not
learn using pictures or by seeing things.
• The best part of doing things this way is that
we all get to eat doughnuts if we are patient.

3. Volunteers needed to put on hats and
gloves:
• One nucleus (me)
• One cell membrane (hat)
• One mitochondria (hats)
• Two ribosomes (hat and gloves)
• Three Endoplasmic Reticulum (hats and gloves)
• Two Golgi Apparatus (hats and gloves)
• Two Vacuoles (hats)
• Two lysosomes (hats)
• Everyone else can be the cytoplasm!
• Turn off classroom lights to get started.

4. Proteins
• All cells make proteins in order to live and use
them for everything they do.
• Our cell today is a Krispy Kreme Shop, and the
proteins made by our cell are called
doughnuts.
• I am going to show you how each part of the
cells helps to make the doughnuts.
• We can’t eat them yet.

5. Cell Membrane
• In a cell, the cell membrane surrounds the cell
and controls what comes in and out.
• In our Krispy Kreme shop, the walls and doors are
like the cell membrane. They only let certain
things in and out, and you can only get in and out
at certain places in the membrane (doors).
• It is good to have a strong cell membrane in our
Krispy Kreme shop today so that other students
don’t come in and steal our doughnuts.

6. Mitochondria
• In a cell, mitochondria make the energy so that
the cell has power to function.
• At Krispy Kreme, the mitochondria are the
electrical wires from the power station that
supplies power to the shop.
• Nothing can happen until the mitochondria are
ready to supply power.
• Is our mitochondria ready?
• If they say ‘yes’ then they can go ahead and make
energy that turns on the lights and we can get
started.

7. Nucleus
• In a cell, the nucleus controls all functions of
the cell. It is like the brain and it is in charge!
• At Krispy Kreme, the manager is the nucleus
because he or she is in charge and makes all
the other parts of the cell do their jobs.
• I met the manager of the Krispy Kreme on
Stratford Road. He gave us the supplies. His
name is Junior.

8. Nucleus
• In a cell, the nucleus contains DNA that is like
an instruction book on how the cell should live
and function.
• At Krispy Kreme, the recipe book is like DNA
and tells the manager (the nucleus) how to
make doughnuts!

9. Ribosomes
• In a cell, a ribosome use ingredients called
amino acids and makes proteins. The nucleus
gives the instructions.
• At Krispy Kreme, the doughnut making
machine is the ribosome. The manager gives
the instructions and then the machine puts all
the ingredients together and makes the
doughnut.

10. Endoplasmic Reticulum
• In a cell, the endoplasmic reticulum is like a
tunnel. A ribosome makes the protein, spits it
into the endoplasmic reticulum tunnel to
transport it to the next step.
• At Krispy Kreme , the finished doughnuts are
transported along a moving belt. This is the
endoplasmic reticulum.
• One day I would like to touch the giant
doughnut machine.

11. Golgi Bodies
• In a cell, the Golgi bodies receive the proteins
from the endoplasmic reticulum and package
them.
• In our Krispy Kreme shop, the workers get the
doughnuts off the belt and package them in
bags and boxes. They are like the Golgi bodies.

12. Vacuoles
• In a cell, vacuoles store lots of important
things for the cell, like water and other
materials.
• In our Krispy Kreme shop, we have vacuoles
that store napkins and drinks that are
necessary when eating our doughnuts.
• Would the vacuoles and Golgi bodies please
distribute their materials to the rest of the
cell?

13. Lysosomes
• The lysosomes are like the workers who clean up
and throw away left-overs plus recycle the boxes.
• Guess what the lysosomes get to do in our Krispy
Kreme shop today?
