Plant Cell Models
Objective: - Describe the role of cells as a basic unit of life.
- Distinguish between plant and animal cells.
Cells are the basic unit of life and their structures play a vital role in how
each cell functions. The structures inside a cell are quite unique as they each
perform a different role to make the cell work. These individual structures inside
the cell are called an organelle. Plants and animals are different at the cellular
level in a few ways, but they do have a lot of similarities. In this activity you will
build and illustrate a model plant cell, explain the function of each organelle, and
distinguish between plant and animal cells.
Procedure:
1. Obtain the materials for the activity listed below:
a. 1 – zip lock bag of icing = glue
b. 2 – pop tarts = base of the cell
c. 1 – Oreo cookie = nucleus
d. 3 – coke bottles = mitochondria
e. 2 – pieces of red liquorice = cell membrane
f. 2 – pieces of green liquorice = cell wall
g. 1 – brazil nut = vacuole
h. Leave empty spaces on the pop tart = cytoplasm
i. 3 – green jelly beans = chloroplasts
2. Assemble a cell model that uses the above components to represent each organelle.
3. Use the blank sheet of paper to illustrate your cell model. It should include
i. A diagram of the model cell
ii. Labels for each part of your cell
iii. A title, your name, and the date
4. In the table below you will write the function of each organelle.
- Use page 108 of your text to help you.
