PLANT CELL
Making a Cell Model
Due Date_____________________________
Assignment :
Construct a model of a cell that demonstrates your knowledge of
cell parts and their relationship to each other in the cell.
Choose one only…plant cell or animal cell. Once you decide
which type of cell you will create a model of, you will have to
decide what kind of model to make. You may choose from the
following:
a. a clay model $$$
b. a styrofoam model $$
c. a plastic baggie model $
Guidelines for each model type are attached.
All parts must be labeled (if possible), and your model must be
accompanied by a neatly printed or typed sheet listing all required
cell parts along with a description of what they look like, what their
function is in the cell and how they fulfill their function. (If you are
doing the plastic baggie model, you will have to identify which
item represents which part. For example…cell wall-green Saran
Wrap).
Example (from a plant cell):
Cell Wall: (Green Saran Wrap)- A cellulose layer that surrounds the plasma
membrane of plant cells. Because it is very porous, the cell wall is permeable to
molecules and ions that cannot pass through the plasma membrane by simple
diffusion. During plasmolysis, the cell membrane loses water and its contents shrink
up into a ball, while the outer cell wall remains intact. Shrubs and trees have a
thickened secondary cell wall containing lignin, a brown phenolic polymer that
imparts great strength and hardness to wood. Ironwoods such as lignum vitae sink in
water because of the density of their heavy, thick-walled, lignified cells.

The cell diagrams on the first page were copied from the website
in “b”.
Materials can be obtained from the grocery store, a craft store,
and/or a “99 Cent” store.
You will be graded on:
1. Neatness
2. Accuracy…you must include all of the required parts and
label them clearly (labels not required on the plastic baggie
model). Additionally, your “write-up” must also include all of the
required parts and have complete descriptions for each one.
3. Timeliness…your model must be turned in on time!
4. Effort…if it looks “thrown together”, your grade will be lowered.
The attached diagrams (page 1) show what your cell should
look like and which organelles and other cell parts must be
identified.
The model must not exceed 10”wide x 10” deep by 10”long.
1. Modeling Clay Method:
Purchase various colors of modeling clay (do not use Play-Doh)
at Michaels or other craft store. You will need a larger quantity of
whichever color you decide to use for the cell membrane. Using
various colors of clay, form shapes that look like each part of the
cell. Using toothpicks or glue, affix each clay “part” to the clay cell
membrane. Use a toothpick flag to label the “parts”.
2. Styrofoam Model:
Purchase a styrofoam “ball” (animal cell) or rectangle (plant cell)
at a craft store. Use household items like macaroni noodles,
candy, buttons etc. to represent the organelles (cell parts) in the
cell. Be creative! Label the parts with toothpick flags.
3. Plastic Baggie Model:
Fill a sandwich-size Ziplock bag with corn syrup (cytoplasm). Put
household items (like those mentioned above) in to represent the
organelles (cell parts) contained in the cell. Be creative! You will
probably not be able to label the parts so cross reference them
with their corresponding organelle description on the written list
(Refer back to the “cell wall – green Saran Wrap” example).
