5. Sort the following terms into the correct category below:Terms: Active Transport, Diffusion, Endocytosis, Exocytosis, Facilitated Passive Transport, Osmosis, Passive Transport, Phagocytosis, PinocytosisActive Forms of Cell Transport Passive Forms of Cell TransportActive Transport DiffusionEndocytosis Facilitated Passive TransportExocytosis OsmosisPhagocytosis Passive TransportPinocytosis6. Match the following terms with their definitionsLetter Term DefinitionC Active Transport A. When compared- the solution with greater solute

concentrationG Concentration Gradient B. Membrane chooses what may enter / leaveJ Diffusion C. Movement of materials from low to high conc.

Using protein pumpsL Dynamic Equilibrium D. When compared- solutions have equal solute conc.F Facilitatited Diffusion E. pinching in of cell membrane to take in small ions

and water.A Hypertonic Solution F. Movement of molecules through a membrane from

high to low concentration using protein channels.M Hypotonic Solution G. Differences in concentration on either side of a

membraneD Isotonic Solution H. Membrane pinches off to transport larger moleculesN Osmosis I. Movement of materials from high to low conc. Through

a membrane.I Passive Transport J. Movement of materials from high to low conc.H Phagocytosis K. The outward force exerted by water.E Pinocytosis L. Constant Fluctuations to create equilibrium

between two solutionsK Turgor Pressure M. When compared- the solution with a lower solute

concentration.B Selective Permeability N. Movement of water from a high to low concentration.7. Use the following diagrams To answer questions A-E: 0 min 20 min

A) Why did the amount of water change? Equillibrium needed to be establishedB) Why did the amount of protein stay the same? Protein is too large to pass through the cell membrane.

Protein

A B A B

C) If the 0 min diagram concentration of protein on side A was 12% and side B was 4%. What would the concentration be in the 20 min diagram on side A 8% , side B_ 8% D) At equilibrium water molecules continue to move between the two sides. However the number entering side A is equal to than/to the number entering side BE) In the diagram give one example of: ( Be Specific) a) isotonic Side A vs. B in the 20 min diagram b) hypotonic: Side B compared to A in the 0 min diagram c) hypertonic: Side A compared to B in the 0 min diagram8. Given : Solution A: 100 mL water Solution C: 90 mL water & 10g saltSolution B: 95mL water & 5 g salt Solution D: 45 mL water & 5 g salt* note 1mL of water = 1 gFill in the blank with one of the following words: Hypertonic, Hypotonic or Isotonic

a) Solution A is _ Hypotonic _compared to solution Bb) Solution C is _ Hypertonic _compared to solution Bc) Solution D is _Hypertonic _compared to solution Ad) Solution D is _Isotonic _compared to solution Ce) Solution B is Hypotonic compared to solution C

9. Use the following information for the next question: * Note: Too much salt is toxic to cells

Beaker A

Beaker B

Beaker C

Beaker D

% Salt Solution in cells 1% 1% 0.1% 0.1%% Salt Solution in water surrounding cells 1% 0.1% 1% 0.1%Which of the above illustrates active transport? _Beaker C Explain: The cell is using energy to minimize the amount of salt that is internalized10. Why does grass wilt if it is over fertilized? Outside solution is hypertonic with a lot of fertilizer minerals. Water water is pulled by osmosis from where the water concentration is higher ( Inside the plant cells) to where the water concentration is lower (in the surrounding soil) 11. A marathon runner collapses after running on a hot day. Although the runner consumed water along the route, analysis shows that many of the runner’s red blood cells burst. Explain. ( Hint: along the route only pure water was available) With only pure water taken in ( no salts) the solution outside of the red blood cells is hypotonic. Water travels from the hypotonic solution (high water- outside) to the hypertonic solution ( low water- inside). The rush of water causes cell bursting.

The following web sites have good review practice for cells and cell transport.

Biology a guide to the online worldhttp://cwx.prenhall.com/bookbind/pubbooks/krogh3/*Chapter 4 Cells and Chapter 5 The Cell Membrane ( Transport) has a basic quiz and achallenge quiz ( as well as links)

Online Biology Bookhttp://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookTOC.html*Chapter 5 (Cells) and Chapter 6( Transport) has readings and great diagrams of the organelles in the cell as well as some review questions and links. Also has readings and diagrams of types of transport and the cell membrane.
