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

  2. I I I I I I I I PASSIVE TRANSPORT: I I I I I I I I Name Date Period

  3. Cellular transport

  4. CELL TRANSPORT 1. PASSIVE TRANSPORT- cell does not use it’s own energy 2. ACTIVE TRANSPORT- cell uses energy (ATP)

  5. PASSIVE TRANSPORT I I I I I I I I I I I I I I I I Simple diffusion 2. Facilitated Diffusion 3. Osmosis On each topic, include: Definition and picture/illustration

  6. SIMPLE DIFFUSION- Movement of molecules from an area of high concentration to low concentration When one area has a higher concentration than the other a ___________________ exists. Molecules are moved (up or down) their concentration gradient? concentration gradient

  7. Passive Transport Mechanisms(require no energy) A When a space is filled evenly it is considered to be in a state of ___________. equilibrium

  8. Since oxygen is nonpolar, by what means would it pass through the cell membrane? Simple diffusion

  9. FACILITATED DIFFUSION Passive movement using transport proteins: 1. ChannelProteins- ions, sugar, and amino acids 2. Carrier Proteins- substances must fit in their binding site

  10. 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

  11. SOLUTION • Solute + solvent =solution • Solute=substance being dissolved • Solvent=substance doing the dissolving

  12. FLIP FOLDABLE TO THE OTHER SIDE, DIVIDE INTO 3 SECTIONS AND LABEL AS FOLLOWS: HYPERTONIC HYPOTONIC ISOTONIC INCLUDE THE FOLLOWING ON EACH: DEFINITION PICTURE MOVEMENT OF WATER (IN, OUT, OR THE SAME)

  13. Hypertonic Solution • Hyper (solute) =“high” concentration of solutes in the solution • More solutes less water (solvent) • Water moves out and cell shrinks

  14. Hypotonic Solution • Hypo (solute) =“low” concentration of solutes in the solution • Less solutes more water (solvent) • Water moves in and cell swells

  15. Isotonic Solution • Solutes in cell = solutes outside the cell • Water moves in and out at the same rate (no net movement) • A healthy cell

  16. Contractile Vacuoles: Found in some unicellular eukaryotes, which collect excess water inside the cell and force the water out of the cell

  17. ACTIVE TRANSPORT FOLDABLE TAKE THE UPPER RIGHT HAND CORNER OF THE SHEET OF PAPER AND FOLD IT TOWARDS THE OPPOSITE LEFT SIDE. 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. YOUR FOLDABLE SHOULD LOOK LIKE THE FOLLOWING: _ _ _ _ _ _ _ _ _ _ _ _ _ _ CUT

  18. 4. FOLD EACH CORNER TOWARDS THE CENTER AND LABEL EACH TAB AS FOLLOWS: ACTIVE TRANSPORT NA+/K+ PUMP EXOCYTOSIS ENDOCYTOSIS INCLUDE A DRAWING & DESCRIPTION OF EACH _ _ _ _ _ _ _ _ _ _ _ _ _ _ CUT

  19. Types of Active Transport: Sodium-Potassium Pump-Na+/K+ Endocytosis Exocytosis

  20. Active Transport Requires energy in the form of ____________ to move substances from an area of _________ to ________ concentration. ATP low high

  21. Pumps 3 (Na+) out & 2 (K+) in from an area of low concentration to high

  22. Endocytosis Endo= “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

  23. Exocytosis- “out of cell” Movement of large materials outside of a cell by means of a vesicle
