2 Notes and FoldablesThe first part of the power point should go in your notebookDon’t forget CORNEL STYLE NOTESThe rest of the power point will go in there.
3 Vocabulary (In notebook) Hydrophobic – molecule that does NOT want to be around water ** NONPOLAR (ex: oil)HATES WATERHydrophilic – molecule that wants to be around water -** POLAR (ex: sugar, salts, other waters)LOVES WATER
4 Phospholipids (In notebook) Draw this diagram in your notesPhosphate HeadHYDROPHILIC “Loves Water”HYDROPHOBIC “Hates Water”Lipid Tails
5 Cell (or Plasma) Membrane (In notebook) Phospholipid Bilayers – lipid layers creates a water proof boundary for the cells (Purple Area)
6 Cell (or Plasma) Membrane (In notebook) * Cell membranes control what enters or leaves the cells
7 Vocabulary (In notebook) Solute – a molecule that is being dissolvedEx: salt or sugar will dissolve in waterNOTICE: look how the water molecules orient themselves to the + or – solute ionsNa+ (Sodium Ion)Cl- (Chlorine Ion)
8 Vocabulary (In notebook) Solvent – a molecule that can dissolve somethingEx: Water (the universal solvent)
9 Vocabulary (In notebook) Solution – made up of solvent and solutesSoluteSoluteWaterSolute
10 Vocabulary (In notebook) Concentration Gradient – the difference between molecules (green hexagons) on opposite sides of the membrane
11 Notice the difference between HIGH concentration and LOW concentration
12 IF they can, molecules will ALWAYS try to equal out on both sides
13 Vocabulary (In notebook) Equilibrium – when solute amounts are EQUAL everywhere (usually referring to both sides of a membrane)
14 Vocabulary (In notebook) Permeable – when molecules can cross a membrane
15 Vocabulary (In notebook) Selectively Permeable – when certain molecules are allowed to cross a membrane
19 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
20 Cellular Transport Foldable Write “Cellular Transport” at the bottom of the page (the 1cm section)
21 Cellular Transport Foldable Open the page back up
22 Cellular Transport Foldable Fold the page along the short edge, BUT JUST crease the upper portion in half (crease down the blue dotted line)
23 Cellular Transport Foldable Fold each edge into the middle upper fold you just made and crease only in the upper section again.
24 Cellular Transport Foldable Cut along the dotted lines that are colored blue in this picture

27 Picture for Simple Diffusion Inside Upper Flap HIGH ConcentrationLOW Concentration
28 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)
29 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 students3) a child going down a slide is like moving down the concentration gradient.
30 Picture for Facilitated Diffusion Inside Upper Flap HIGH ConcentrationLOW Concentration
31 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)
32 Facilitated Diffusion (Inside lower flap) The solute molecules are either Too BIG or Too HYDROPHILIC to cross the lipid area of the phospholipid bilayerTransport proteins act as a tunnel that solutes travel through.
33 Picture for Osmosis Inside Upper Flap HIGH ConcentrationLOW Concentration
34 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)
35 Osmosis (Inside lower flap) (Vocabulary) Osmosis – Movement of water across a membraneWater molecules will never be able to easily cross the lipid area of the phospholipid bilayer, but ALL CELLS NEED WATERAquaporin is the transport protein that acts as a tunnel that solutes travel through.
36 2 Pictures for Active Transport Inside Upper Flap NOTICE: There are two pictures for Active Transport. Put one picture above the other on the inside upper flap…Picture 1Picture 2
37 Picture 1 for Active Transport Inside upper flap HIGH ConcentrationATPLOW Concentration
38 Picture 2 for Active Transport Inside upper flap HIGH ConcentrationLOW Concentration
39 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 gradientActive Transport ALWAYS needs energy (ATP)
40 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.
41 Active Transport (Inside lower flap) Active Transport is the only kind of cell movement that REQUIRES energy to work.
42 Tonic Solution Concentration Foldable (Use your other sheet of clean paper)
43 Tonic Solution Concentration Foldable In landscape orientation again, fold your sheet of paper along the long edge leaving about 1cm (one finger width) at the bottom of the page
44 Tonic Solution Concentration Foldable Write “Tonic Solution Concentration” at the bottom of the page (the 1cm section)
45 Tonic Solution Concentration Foldable Open the page back up
46 Tonic Solution Concentration Foldable Fold over 1/3 of the page ( the folded section is about equal length to the non-folded section) and crease the top section to the middle line
47 Tonic Solution Concentration Foldable Repeat on the other side, folding the edge to the first crease to make the 2nd crease
48 Tonic Solution Concentration Foldable Cut along the blue dotted lines

One for plant cells one for animal (blood) cells. DO NOT MIX UP THE PICTURES WITH WRONG DESCRIPTIONS
52 Types of osmotic solutions Hypotonic SolutionHigh water purity (lots of water molecules) & less solutes = water moves in & cell expands and may burst (Cytolysis)Isotonic SolutionEqual solutes & water molecules, so equal movement of water into and out of the cellHypertonic SolutionLow water purity (few water molecules) because of more solutes = water moves out & cell shrinks (Plasmolysis)
