WARM-UP:
INSTRUCTIONS FOR PASSIVE TRANSPORT FOLDABLE:
1. FOLD THE SHEET ON YOUR DESK HOT DOG-STYLE.
2. CUT TWO SLITS ON THE FRONT FLAP TOWARDS THE FOLD IN THE CENTER, MAKING 3 PANELS (3 FLAPS)
3. Turn to pg 201

CELL TRANSPORT
1. PASSIVE TRANSPORT- cell does not use it’s own energy
2. ACTIVE TRANSPORT- cell uses energy (ATP)
PASSIVE TRANSPORT1. Simple diff usion
2. Facilitated Diff usion
3. OsmosisIIIIIIII
IIIIIIII
On each topic, include:Definition and picture/illustration
SIMPLE DIFFUSION-
1. When one area has a higher concentration than the other a ___________________ exists.
2. Molecules are moved (up or down) their concentration gradient?
Movement of molecules from an area of high concentration to low concentration
concentration gradient
Passive Transport Mechanisms(require no energy)
A
When a space is filled evenly it is considered to be in a state of ___________.equilibrium
Since oxygen is nonpolar, by what means would it pass
through the cell membrane?
Simple diffusion
FACILITATED DIFFUSIONPassive movement using
transport proteins:
1. Channel Proteins- ions, sugar, and amino acids
2. Carrier Proteins- substances must fit in their binding site
OSMOSIS:Diffusion of water through a selectively permeable membrane
*Osmosis allows cells to maintain water balance as their environment changes
*As a result water moves _______ the concentration gradient
down
SOLUTION
• Solute + solvent =solution
• Solute=substance being dissolved
• Solvent=substance doing the dissolving
FLIP FOLDABLE TO THE OTHER SIDE, DIVIDE INTO 3 SECTIONS AND LABEL AS FOLLOWS:
1. HYPERTONIC2. HYPOTONIC3. ISOTONIC
INCLUDE THE FOLLOWING ON EACH:4. DEFINITION5. PICTURE6. MOVEMENT OF WATER (IN, OUT, OR THE SAME)
Hypertonic Solution
• Hyper (solute) =“high” concentration of solutes in the solution
• More solutes less water (solvent)
• Water moves out and cell shrinks
Hypotonic Solution
• Hypo (solute) =“low” concentration of solutes in the solution
• Less solutes more water (solvent)
• Water moves in and cell swells
Isotonic Solution
• Solutes in cell = solutes outside the cell
• Water moves in and out at the same rate (no net movement)
• A healthy cell
Contractile Vacuoles:
Found in some unicellular eukaryotes, which collect excess water inside the cell and force the water out of the cell
ACTIVE TRANSPORT FOLDABLE1. TAKE THE UPPER RIGHT HAND CORNER OF THE SHEET OF PAPER AND FOLD IT
TOWARDS THE OPPOSITE LEFT SIDE.
2. OPEN IT UP AND NOW TAKE THE UPPER LEFT HAND CORNER AND FOLD IT TOWARDS THE OPPOSITE RIGHT SIDE. CUT OFF THE EXCESS PAPER OUTSIDE OF THE SQUARE.
3. YOUR FOLDABLE SHOULD LOOK LIKE THE FOLLOWING:

EXOCYTOSIS
4. FOLD EACH CORNER TOWARDS THE CENTER AND LABEL EACH TAB AS FOLLOWS:
INCLUDE A DRAWING & DESCRIPTION OF EACH
Types of Active Transport:
1. Sodium-Potassium Pump-Na+/K+
2. Endocytosis
3. Exocytosis
Active Transport
Requires energy in the form of ____________ to move substances
from an area of _________ to ________ concentration.
ATPlow
high
Pumps 3 (Na+) out & 2 (K+) in from an area of low concentration to high
EndocytosisEndo= “into”
Movement of large particles such as proteins and polysaccharides into the cell
1. Phagocytosis –”cellular eating” uptake of solid particles (food)
2. Pinocytosis – “cellular drinking” uptake of fluids
Exocytosis- “out of cell”
Movement of large materials outside of a cell by means of a vesicle
