Cell Analogies Angie Karnes
November 2012
Do Now “Think-Pair-Share”Review Question #1:A student looks under the microscope and sees the following image.
a) Is it a plant cell or an animal cell?
b) How do you know? (Evidence)
Review Question #2:a) Is it eukaryote or prokaryote?
b) How do you know?
With your partner: A Cell is Like…What do you
notice/see in the picture?
What do you think it is trying to show
you?
What questions does it raise?
SLIDE 1:Why is a cell like a factory? The job of a factory is to make a product
(i.e. a bicycle, a cellphone, etc.) The job of a cell is to make proteins (i.e.
hemoglobin, melanin, insulin, etc.)
As a Class: Notes on Cell Analogies
The cell wall is like the security gates because….
◦ It surrounds the factory and protects it just as a cell wall surrounds a plant cell and maintains structure.
Slide 2:
The cell membrane is like the door because….
◦ It allows materials to enter and leave the factory
Slide 3:
The nucleus is like the CEO/boss because….
◦ It controls the factory and tells it what to do
Slide 4
The cytoplasm is like the factory floor because….
◦ It fills up the factory and connects each location to another
Slide 5:
The Endoplasmic reticulum is like the assembly line because…
◦ It moves the product (proteins) around
Slide 6:
The Ribosomes is like the factory workers because…
◦ They make the products (just like they make the protein)
Slide 7:
The Vacuole is like the Kitchen because…
◦ It stores food/water for the workers
Slide 8:
The lysosomes are like the custodial staff because…
◦ They clean up the factory’s waste materials, disinfect, etc.
Slide 9:
The mitochondria is like the generator because…
◦ It provides energy for the factory’s machines
Slide 10:
Your goal: To create your own cell analogy.
Part A. Cell Analogy Brainstorm Activity Directions: Decide what you want to compare a cell to. For example, remember how we compared the cell to a factory? What other analogy can you come up with? A cell is like a

Complete a chart for your analogy
Create a visual representation of your analogy. Use the large paper for this.
Your visual MUST include the following FOUR components: Title “A cell is like ______________” Your name Each picture/organelle labeled clearly A brief description of why its an analogy.
Example: “The Gatorade is like the mitochondria because it
provides energy to the players”
Part B. Create your Visual
Write a 1-2 page response to the following 4-5 questions:1. What are cells?2. What kinds of cells exist? 3. What are organelles? (Provide a few examples and explain their function)4. How do plant cells differ from animal cells?5. What analogy did you select for this project, and why?
***Note: If you need to look information up on the internet, remember to PARAPHRASE (put it in your OWN words. Students who copy off of the internet will automatically receive a zero on the written component.
