Cell Wall Cell Membrane Location (Plant, Animal, or Both?) Structure (What is it like?) Function (What does it do?) (What does it do?) Journal Question: 19 Nov 2012 Please complete this chart and question on a blank notecard. How are a Cell Wall and a Cell Membrane DIFFERENT from each other?

Slide 2

Did you knowcells have jobs too?!?!

Slide 3

Position: Quarterback Job Description: calls the plays and hands off/passes the ball to teammates

Slide 9

Do all of these players have the same purpose???NO! and neither do cells. Cells are specialized like players on a football team with specific functions or jobs.

Slide 10

Can you think of cells that we have studied in class with a special purpose? Here are some HINTS

Slide 11

The structure of a cell (whats inside or how it is shaped) can tell us a lot about what the function or job of that cell is. Just like the players on the football team, a wide receiver is going to have a very different body type from an offensive lineman.

Slide 12

Design a cell that would fit the functions listed below. Consider the following: How does the way it looks or what it contains help it to fulfill its job? Job Description: Roams the body looking for foreign invaders Attacks/engulfs foreign invaders it meets Digests and destroys invaders that it engulfs

Slide 13

(a kind of white-blood cell and part of your immune system)

Slide 14

What kind of cells are these? Red blood cells What is its function/job? Carries oxygen around the body Why do you think it looks the way it does? (How does its shape relate to its job?)

Slide 15

What kind of cell is it? A nerve cell What is its function/job? Sends signals/impulses around the body Why do you think it looks the way it does? (How does its shape relate to its job?)

Slide 17

Do you agree or disagree with the following statement: All cells look and function the same. Explain with EVIDENCE to support your answer why you agree or disagree with the statement. Come up with one more specialized cell and describe its function?
