Biol Cell Transport Problems Key

Name, Date, Hr/Per hey Cellular Transport Worksheet Answer the following questions using your notes and your textbook. -outside cell Write the correct type of solution underneath (isotonic, hypertonic, or hypotonic) =solute OSMOSIS 3. When the concentration of solute inside & outside a cell is the same, the cell has reached A. maximum concentration C. osmotic pressure B. homeostasis D. dynamic equilibrium 4. The diffusion of water across a selectively permeable membrane is called A. active transport B. facilitated diffusion. Cosmosis D. phagocytosis 5. Energy for active transport comes from a cell's. B. nucleus D. lysosomes haype hyper 3. there is a GREATER concentration of solute molecules OUTSIDE the cell than inside. 4. Hypertonic s. Hupo tonic there is a LOWER concentration of molecul solute molecules OUTSIDE the cell than inside. 6. 150 tonic there is the SAME concentration of solute molecules outside the cell as inside. Cells swell and burst 8. What organelle [that plants have that animals don't] keeps plant cells from bursting in this condition? all wall 7. The SWELLING AND BURSTING of animal cells when water enters happens when a cell is placed in a tonic solution. 9. The SHRINKING of plant cells when water leaves so the cell membrane pulls away from the cell wall or shrinking of animal cells happens when a plant cell is placed into a hypertonic solution. ال 10. Cells stay the same size when placed in an 150 tonic solution because the amount of water leaving the cell is the same and the amount of water entering. MULTIPLE CHOICE: Circle and/or fill-in the answer(s) that best completes the sentence. to make a solution is called the 1. The substance that dissolves A. diffuser B. solvent 2. During diffusion molecules tend to move A. up/against the concentration gradient B. from an area of lower concentration to an area of higher concentration D. concentrate C/down/ with the concentration gradient D. in a direction that doesn't depend on concentration A. Golgi complex mitochondria A. Passive transport requires energy from ATP to move substances across membranes. B. Active B. facilitated diffusion Dion channels 7. All of the following are kinds of passive transport EXCEPT A. Diffusion B. Osmosis 8. When molecules move DOWN the concentration gradient it means they're moving from A, an area of low concentration to an area of higher concentration an area of high concentration to an area of lower concentration Fill-Ins-Complete the transport terms. Some of the letters have been filled in! 1. Active transport requires Elecay to move molecules across membranes. 2. AIP is the molecule that provides the energy for active transport. 3 . Diffusion moves oxygen and carbon dioxide molecules from a high concentration to a low concentration across membranes. The cell organelles that burns glucose and provides ATP for active transport are the 4. Mikochendr 5 6. A small membrane sac used to transport substances during exocytosis & endocytosis . Water moves across membranes by Q vesicle 7 PASsive transport does NOT REQUIRE energy. outsider A cell placed in an setinis solution neither swells or shrinks because the concentration of molecules outside the cell is the same as inside. CellA solution in which there is a HIGHER concentration of molecules OUTSIDE the cell than Inside = Hypetenc 10 A CONCENTRATION GLA dien concentration between one place and another. 11. A solution in which the concentration of molecules outside the cell is LOWER than inside solute forms whenever there is a difference in solute 12. When molecules move from high to low along a concentration gradient we say they are moving "DO" the gradient. 13. osmoti (pressure is caused by water inside a plant cell pushing against the cell wall. B LOOK AT THE DIAGRAMS-The black dots represent solute molecules dissolved in water I. In which beaker is the concentration of solute the greatest? B 2. If the solute (dots) in this diagram is unable to pass through the dividing membrane, what will happen? A the water level will rise on the right side of the tube B. the water level will rise on the left side of the tube C. the water level will stay equal on the two sides Examine the pictures on the bottom of the left side of this page. What if anything) is different about the plant and animal cells in each of these states? State Hypertonic Animal Cell Shrinks Isotonic no change Plant Cell Shrinks inside cell wall no change Hypotonic swells & bursts swells Matching-Match each term to its definition. Match the description with the solution type: solution with a lower solute concentration (more water) solution in which the solute concentration is the same a. energy condition plant cells require A. Isotonic B. Hypertonic CHypotonic condition that animal cells require red blood cell bursts (cytolysis) 5 plant cells shrink (plasmolysis) 7 solution with a high water concentration solution with a higher solute concentration (less water) Joutside cell Label the tonicity for each solution sotonic, hypotonic, or hypertonic): Pay close attention to the arrows!!! b. facilitated diffusion endocytosis d. passive transport eactive transport exocytosis gprotein ion pump hchannel protein Short Answer- 42 Is used during active transport but not passive transport Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse 3. Process by around it which a cell takes in material by forming a vacuole D4. Particle movement from an area of higher concentration area of lower concentration to an 5. Process by which a cell expels wastes from a vacuole 6. A form of passive transport that uses transport proteins 57. Particle movement from an area of lower concentration to an area of higher concentration 8.Transport protein that changes shape when a particle binds with it 1. Name two factors that affect the rate of diffusion. Temperature, Concentration Gradient Hype Iso hyper Hypo Iso Hyper
