Learning Target Write it down I can explain why all cells do NOT look the same.
Percy Harvin • Position: Wide Receiver • Job Description: Catches passes and runs with the ball
Adrian Peterson • Position: Running Back • Job Description: Takes handoffs and runs with the ball
Jared Allen • Position: Defensive End • Job Description: Sack the quarterback
Ryan Longwell • Position: 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 Think Can 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 Cells • What kind of cell is it? • Red blood cell • What 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 Cells • What kind of cell is it? Nerve cell • What is its function/job? Carry signals (messages) around the body • Why do you think it looks the way it does? Long= signals go far away Branched = signals go to many cells at once
Some Examples of Specialized Cells • What kind of cells are these? • Skin cells • What is its function/job? • Protects our insides • Why do you think it looks the way it does? • Flat & Layered = keeps outside stuff from getting inside!
Quick Check “All cells look and function the same.” Explain (with EVIDENCE) why you agree or disagree with the statement. I agree/disagree because…
Specialized Cell Comparisons - Start a New Page - Add it to your TOC
Specialized Cell Comparison We are going to be reading about different kinds of specialized cells. • You will be given a group number. • Choose any article with the same number. • Read and complete the chart (left side) • Share to complete right side (with a different type of cell).
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
Macrophages One type of white-blood cell Part of your immune system – helps fight invaders!
Quick Check • Write the chemical reaction for Photosynthesis.(show what goes in AND what comes out) • Write the chemical reaction for Respiration. (show what goes in AND what comes out)
