Specialized CellsCells have jobs too!!

Learning TargetWrite it down

I can explain why all cells do NOT look the same.

Percy HarvinPosition: Wide Receiver

Job Description: Catches passes and runs with the ball

Adrian PetersonPosition: Running Back

Job Description: Takes handoffs and runs with the ball

Jared AllenPosition: Defensive End

Job Description: Sack the quarterback

Ryan LongwellPosition: Kicker

Job Description: Kicks field goals

So what…?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.

Quick ThinkCan you think of cells that we have studied in class with different jobs?

Here are some HINTS

Structure and Function

Structure: what something is like (both inside and out)

Texture, Shape, Color, Strength, etc.

Function: what something does (its job)

Structure and Function of a Cell

The structure of a cell can tell us a lot about what the function of that cell is.Just like the players on the football team, a defensive end is going to have a different body type from a kicker.

Some Examples of Specialized CellsWhat kind of cell is it?

Red blood cellWhat is its function/job?

Carry Oxygen (and CO2) around the body

Why do you think it looks the way it does?

Round = doesn’t get stuck!

Some Examples of Specialized CellsWhat kind of cell is it?

Nerve cellWhat is its function/job?

Carry signals (messages) around the body

Why do you think it looks the way it does?

Long = signals go far awayBranched = signals go to

many cells at once

Some Examples of Specialized CellsWhat kind of cells are these?

Skin cellsWhat is its function/job?Protects our insidesWhy do you think it looks the way it does?Flat & Layered = keeps

outside stuff from getting inside!

Design a Specialized Cell…

Draw a cell for the functions listed below.Be Creative! Draw whatever you think of!!! Think about:

How does the way it looks help it to fulfill its job?How do its parts (inside and outside) help it do its job?

Job Description:• Roams the body looking for foreign invaders• Attacks/engulfs foreign invaders it encounters• Digests and destroys invaders that it engulfs

MacrophagesOne type of white-blood cell

Part of your immune system – helps fight invaders!
