Edible Cell Mitosis
Materials:
3 colours string licorice (2 strings of each)
2 Hershey’s kisses
4 Nibs
2 pairs of gummy worms
Directions:
1. Place a few pieces of paper on your desk so that the candy does not come in
contact with your desk.
2. IMPORTANT: At each stage take a picture
the next one.
before you move on to
3. Interphase: Create a cell that is in interphase.
a. Use one colour of string licorice to make the cell membrane. Wrap the
entire string around to make the circle.
b. Use half of the other colour string licorice to make the nuclear
membrane in the centre of the cell.
c. Place two gummy worms inside the nucleus. These are the
chromosomes.
d. Add a Hersey’s kiss to the nucleus. This is your nucleolus.
e. Place two nibs next to each other in the cell. This is your pair of
centrioles within the centrosome.
4. In Interphase the cell grows and replicates its DNA.
a. Add another piece of licorice to the cell membrane and the other half
of the nuclear membrane licorice to the nuclear membrane to make
each circle larger.
b. Add two more gummy worms into the nucleus. Make sure that identical
gummy worms are placed beside each other. Each gummy worm now
represents a sister chromatid and a pair of gummy worms represents
a chromosome.
c. At this point the centrosome also replicates. Place another two nibs
besides the first two.
5. Your cell is now going to go through Mitosis
a. Prophase
i. Move the centrosomes with the centriole pairs to opposite side
of the cell.
ii. Rip off four pieces of string licorice that are long enough to
reach from the centrosomes to the middle of the cell. Place two
strings beside each centrosome. These strings are now your
spindle fibers.
iii. Remove your nuclear membrane.
iv. Separate your chromosomes into pairs of touching sister
chromatids.
v. Remove the nucleolus.
b. Metaphase
i. Tie each spindle fiber to one of the chromosomes. Two spindle
fibers from the opposite centrosomes should be attached to
one chromosome. The point of attachments is called the
centromere.
ii. Pull the chromosomes until they line up in the centre of the cell.
c. Anaphase
i. Separate the sister chromatids from each other.
ii. Using the spindle fibers, have one person pull two of the newly
formed chromosomes to one side of the cell while the other
person pulls the other two chromosomes to the other side of
the cell.
iii. Each side of the cell should now have chromosomes that have
the same appearance.
d. Telophase
i. Pinch the cell membrane together in the centre of the cell to
make two circles. Separate the circles from each other. This is
called Cytokinesis. You now have two daughter cells.
ii. Reform the nuclear membrane in each daughter cell.
iii. Put the chromosomes in random order inside the nucleus.
iv. Place a nucleolus inside each nucleus.
v. Place the centrosome with the pair of centrioles near the
nucleus.
vi. Remove the spindle fibers. (You may now eat them)
Your cell is now finished Mitosis and each daughter cell can grow and begin the
process again.
You may eat the rest of the candy!!! 
6. You should have collected six pictures throughout this process. Please copy
these onto a computer and place them on a word document in the correct
order that they occur. Label each phase and print. Remember to include the
group members’ names. Hand in to Mrs. Graham.
