We need to review these organelles AND
come up with High School Analogies (the
third column) to help us memorize their
functions.
Follow along and add to your last column!

LEARNING OBJECTIVE:
We will learn the structure and function of the cell
membrane.

WHAT IS THE FUNCTION OF THE CELL
MEMBRANE?

Starch Iodine Lab


We have not done many labs yet this
year. Please demonstrate that we can do
MANY more by following the directions
on your handout and listening to ALL
instruction.
This is GROUP work. While that means
that you should be talking, you should
only be talking with your lab group.
Hold your wee for a Wii.


Can water kill?
Is it good to have TOO MUCH of
anything in our body?
What do we call the processes that keep
our body at a constant internal balance?
The Cell Membrane
What are the parts of the Cell
Membrane?
Double layer of
phospholipids
and embedded
molecules which
allow for
selective
permeability
•only some
things can
pass through
What is a phospholipid?
Hydrophillic Head
(I <3 water)
Hydrophobic Tails
(I H8 water)
Retro QUESTION!
Which macromolecule makes up the cell
membrane? Why?
Which organelle makes that macromolecule
for the cell membrane?
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.
Why does the cell membrane control
transport into and out of the cell?





The membrane cannot totally separate the cell from its
environment.
(An analogy: A house’s walls and roof maintains support and protection to the people inside. But, there has
to be a door in order for the people to survive inside).
Water, oxygen, and nutrients must pass through the
membrane and go into the cell.
Waste products must pass out of the cell.
Molecules can enter or leave the cell through:
 Passive
 Active
transport
Selectively Permeable
If a membrane is
selectively permeable
only certain things can
pass through
Passive Transport
Passive
Diffusion
Osmosis
Facilitated
Diffusion
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.
What is diffusion?





Molecules are always moving.
Molecules want to be evenly spaced out (most of the
time, they aren’t)
When the amount of molecules is greater in one part
of a substance, molecules will spread out until they are
evenly spaced.
Diffusion is the movement of molecules from areas of
high concentration to areas of low concentration.
Diffusion requires NO outside energy (like a sled
moving downhill)
Diffusion Activity
diffusion
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.
Which side is high concentration?
Which side is low concentration?
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.
Which direction are the molecules
moving (in diffusion)?
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.
Which direction are the molecules

OSMOSIS
The diffusion of water through
a selectively permeable
membrane
What does that look like???
osmosis
Active Transport: Opening a Door
ATP
ATP

We will learn the structure and function of the cell membrane.
Which side is high concentration?
Which side is low concentration?
LEARNING OBJECTIVE:
We will learn the structure and function of the cell membrane.

We will learn the structure and function of the cell membrane.
Which direction are the molecules

Types of Solutions
What happens when your cells take
in TOO MUCH water?
HYPOtonic Solutions may result in LYSIS
Lysis: When the cell membrane bursts
from too much pressure
Think of a water balloon with too
much water.
Why doesn’t the plant
cell undergo lysis?
