This document discusses cell structure and function. It defines structure as the components something is made of and how they are arranged. Function is defined as what a structure can do or its purpose. For cells, structure determines function. Cells are very small, around 1/100,000 of a square centimeter, and most of what we know about cells has been learned in the last 25 years. The document instructs students to create notecards on cell organelles covering name, function, structure, and sketches to help study them.

1. I. Cell Structure and Function
A. What is meant by STRUCTURE?
1. What it is made of and how its parts are put together.
2. EX: How would you describe the structure of an
acoustic guitar?
made of wood
hollow chamber
long wooden neck
made of six strings
3. In biology...Structure....is determined by how cells are
put together!!

2. B. What is meant by FUNCTION?
1. Function is the what a structure can do or what it´s ‘
purpose is.
2. What is the function of the acoustic guitar?
3. Is the structure related to its function? Why?
4. For living things (organisims)....function means.....
a. Processes that allow the living thing to stay alive
and reproduce.
b. EX: Getting Oxygen
Disposal of waste (getting rid of..)
Obtaining Food
Growing

3. C. SIZE OF CELLS
1. Look at Figure 2 in your Book on page 7..What is the
purpose of this figure?
2. Cells are SMALL!!!....1 cm squared contains 100,000 cells
3. Most of what we know about cells has been learned in the
last 25 years!!!

4. II. Looking inside the Cell
ACTIVITY: WORKING IN GROUPS OF 3
Create a set of notecards to help study cell organelles.
You will need to make 4 cards for each organelle.
1. Organelle Name Card
2. Function Card
3. Structure Card
4. Sketch Card
When you are finished. Mix the cards up on the table and
practice matching organelles with function, structure, and
sketch.

5. CELL MEMBRANE

6. Controls what substances come into
and out of the cell. Ex. waste, oxygen
