MAGNETIC CELL LAB
PRE-LAB
BACKGROUND
A cell is the smallest unit of life. There are two main classifications for cells and
organisms: prokaryotic and eukaryotic. Prokaryotic organisms are comprised of
prokaryotes, or single cells that lack a membrane bound nucleus and usually lack
membrane bound organelles. Cells containing a membrane-bound nucleus and
membrane-bound organelles are classified as eukaryotes. The quantity and types of
organelles in cells depend on the function of the cell. Not all animal cells and plant cells
look or function the same way. The cell models used in this lab are just one type of
generalized animal and plant cell.

MATERIALS
Plant or animal cell kit (1 for each pair of students)
PROCEDURE
1. Remove all pieces of your plant or animal cell from the bag.
2. Place all the organelles on the cell in the proper position.
3. As you build your cell, on your own sheet of paper create a chart of three columns
as below:
Organelle
drawing
Name
Function
Animal
Cell
(y/n)
Plant
Cell
(y/n)
4. Take 10 minutes to complete the chart you created without using any resource
materials.
5. Use your textbook or other resources to complete any organelles for which you are
unsure.
6. When you have completed your chart check with another group who had the cell
you did not have (plant or animal). Include any missing organelles and complete
the last two columns.
7. Complete the analysis questions on the student data sheet.

ANALYSIS QUESTIONS
1. What organelles were found in plant cells that were not in animal cells?
2. Why were the organelles listed in #1 above not needed in animal cells?
3. What organelles were found in animal cells that were not found in plant cells?
4. Why were the organelles listed in #3 not needed in plant cells?
5. List the organelles involved in protein synthesis.
6. List the organelles in the plant cell used in energy production and use.

EXTEND: Choose either the model or the analogy poster
Using household items make a three-dimensional model of a plant or animal cell that meets the criteria
listed below. (Sample items: cereal, balloons, mints, fruit slices, dried fruit, matches, gum balls,
peanuts, rope licorice, jelly beans, sesame seeds, other candies, toothpicks. Craft packages also may
work: clay, beads, pipecleaners..etc)
Choose what type of cell you will build, a typical plant or animal cell. Include this label somewhere on
your model.
Create a KEY or label in some way each part on your model and its function.

Scoring Criteria
Craftsmanship
Model is creative, shows effort
Excellent (3 pts)
Satisfactory (2 pts)
The model is 3 dimensional
Model stays together, not too messy or difficult to move around
Cell Parts
Key, legend, or labeling is easy to use to identify parts on the model
Functions of cell parts included (accurate)
Appropriate material is used so that it looks like the cell part it is modeling
Parts of organized within the cell in their appropriate places
Written Word
Basic grammar, spelling on key and any other writing used in model

Cell Analogy Poster Project
Purpose: An analogy is defined by Webster as “a comparison between two things which
are similar in some respects, but otherwise are different; an explaining of something by
comparing it point by point with something else.”
Materials: poster board, glue, scissors, markers, pens, construction paper, list of
functions of cell organelles
Procedure:
1. Work in groups of 3, unless otherwise instructed.
2. Choose a plant or animal cell to base your collage on. The organelles listed below
must be included.
3. Place a colored picture of your cell in the center of your poster board.
4. You will need to establish a theme for your poster – the cell is a city, the cell is a
school, the cell is a factory, etc.
5. Come up with an analogy for each organelle that shows the similarity between the
organelle’s function and the function of an object related to your theme. Be sure
to explain the reasoning behind your analogies.
(For example: The NUCLEUS IS LIKE THE BRAIN because it controls and
coordinates the activities of the whole cell IN THE SAME WAY the brain
controls and coordinates activities of the body.)
Very important note: Your analogies must be in the same format as the one above.
Make sure that you clearly explain your analogy.
6. Around the edges of the poster board; neatly write by hand (or type) the names of
the organelles and your analogy. Make a pointer from the analogy to the correct
organelle in your cell.
7. Projects will be graded based on all organelles being present, correctness of
analogies, correct labeling, the following of all procedures, creativity, and
quality.
