Notes and Foldables
• The first part of the power point should go
in your notebook
– Don’t forget CORNEL STYLE NOTES
• The rest of the power point will go in there.
Vocabulary (In notebook)
• Hydrophobic – molecule that does NOT want to
be around water ** NONPOLAR (ex: oil)
–HATES WATER
• Hydrophilic – molecule that wants to be around
water -** POLAR (ex: sugar, salts, other waters)
–LOVES WATER
Phospholipids (In notebook)
• Draw this
diagram in your
notes
Phosphate Head
Lipid Tails
Cell (or Plasma) Membrane
(In notebook)
Phospholipid Bilayers – lipid layers creates a water
proof boundary for the cells (Purple Area)
Cell (or Plasma) Membrane
(In notebook)
* Cell membranes control what enters or
leaves the cells
Vocabulary (In notebook)
• Solute – a molecule that is being
dissolved
– Ex: salt or sugar will dissolve in water
NOTICE:
Na+ (Sodium Ion)
Cl- (Chlorine Ion)
look how the
water
molecules
orient
themselves
to the + or –
solute ions
Vocabulary (In notebook)
• Solvent – a molecule that can dissolve
something
– Ex: Water (the universal solvent)
Vocabulary (In notebook)
• Solution – made up of solvent and solutes
Solute
Water
Solute
Vocabulary (In notebook)
• Concentration Gradient – the difference
between molecules (green hexagons) on
opposite sides of the membrane
• Notice the difference between HIGH
concentration and LOW concentration
High Concentration
Low Concentration
• IF they can, molecules will ALWAYS try to
equal out on both sides
Vocabulary (In notebook)
• Equilibrium – when solute amounts are
EQUAL everywhere (usually referring to
both sides of a membrane)
Vocabulary (In notebook)
• Permeable – when molecules can cross a
membrane
Vocabulary (In notebook)
• Selectively Permeable – when certain
molecules are allowed to cross a
membrane
• The rest of the slides go into
your foldables…
Cellular Transport Foldable
• Show Landscape vs Portrait orientation
Cellular Transport Foldable
While holding the paper in Landscape orientation, fold your sheet of paper along
the long edge, but leave about 1cm (one finger width) at the bottom of the page
Cellular Transport Foldable
Cellular Transport
Write “Cellular Transport” at the bottom of the page (the 1cm section)

Fold the page along the short edge, BUT JUST crease the upper portion in half
(crease down the blue dotted line)

Cellular Transport
Fold each edge into the middle upper fold you just made and crease only in
the upper section again.

Cellular Transport
Draw the pictures and describe the transport from the following slides…
Picture for Simple Diffusion
Inside Upper Flap
HIGH Concentration
LOW Concentration
Simple Diffusion
(Inside lower flap)
• (Vocabulary) Diffusion - ALWAYS moves
solutes from High Concentration  Low
Concentration
(Down the concentration gradient)
• Simple diffusion allows molecules to move
through the phospholipid bilayer without
needing help.
• Diffusion NEVER needs energy (ATP)
Simple Diffusion
(Inside lower flap)
• Examples:
• 1) perfume/cologne will diffuse through the
entire room when someone sprays it.
• 2) if the room catches on fire, the students
will diffuse from inside (High concentration) to
outside (Low concentration) of students
• 3) a child going down a slide is like moving
down the concentration gradient.
Picture for Facilitated Diffusion
Inside Upper Flap
HIGH Concentration
LOW Concentration
Facilitated Diffusion
(Inside lower flap)
• Facilitated Diffusion ALWAYS moves from
High Concentration  Low Concentration
(Down the concentration gradient)
• (Vocabulary) Facilitated diffusion REQUIRES a helper transport protein to get
solute molecules across the phospholipid
bilayer.
• Facilitated Diffusion NEVER needs energy
(ATP)
Facilitated Diffusion
(Inside lower flap)
• The solute molecules are either Too BIG
or Too HYDROPHILIC to cross the lipid
area of the phospholipid bilayer
• Transport proteins act as a tunnel that
solutes travel through.
Picture for Osmosis
Inside Upper Flap
HIGH Concentration
LOW Concentration
Osmosis (Inside lower flap)
• Osmosis ALWAYS moves from
High Concentration  Low Concentration
(Down the concentration gradient)
• Osmosis REQUIRES a helper transport
protein to get WATER molecules (
)
across the phospholipid bilayer.
• Osmosis NEVER needs energy (ATP)
Osmosis (Inside lower flap)
• (Vocabulary) Osmosis – Movement of water
across a membrane
• Water molecules will never be able to easily
cross the lipid area of the phospholipid
bilayer, but ALL CELLS NEED WATER
• Aquaporin is the transport protein that acts
as a tunnel that solutes travel through.
2 Pictures for Active Transport

• NOTICE: There are two
pictures for Active
Transport. Put one
picture above the other on
the inside upper flap…

Picture 2 for Active Transport
Inside upper flap

LOW Concentration
Active Transport (Inside lower flap)
• Active Transport ALWAYS moves from
LOW Concentration  HIGH Concentration
(AGAINST the concentration gradient)
• (Vocabulary) Active Transport- ALWAYS
REQUIRES ENERGY (ATP) and a helper
transport protein to get solute molecules across
the phospholipid bilayer AGAINST the
concentration gradient
• Active Transport ALWAYS needs energy (ATP)
Active Transport (Inside lower flap)
• Ex: Think of a bouncer at a popular club.
When the cell (club) is full, and a
solute (person) wants to try and get in,
they have to PAY the bouncer to let them
“sneak” by.
Money would be like the cell paying ATP
energy to make the protein channel
(bouncer) let the solute (person) in.
Active Transport (Inside lower flap)
• Active Transport is the only kind of cell
movement that REQUIRES energy to
work.

Divide the bottom sections into 2 parts for each section.

DO NOT MIX UP THE PICTURES WITH WRONG DESCRIPTIONS
Types of osmotic solutions
Hypotonic Solution
• High water purity (lots of water molecules) &
less solutes = water moves in & cell expands and
may burst (Cytolysis)
Isotonic Solution
• Equal solutes & water molecules, so equal
movement of water into and out of the cell
Hypertonic Solution
• Low water purity (few water molecules) because of
more solutes = water moves out & cell shrinks
(Plasmolysis)
