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.
