<p> Cellular Transport Web Quest: </p><p>Name: Date: Period: </p><p>Objective: By the end of the class students will diagram and explain the process of cellular transport, both passive and active. </p><p>All links are provided, in order at: www.mrgittermann.weebly.com</p><p>Part 1: 1. Go to: http://www.wiley.com/legacy/college/boyer/0470003790/animations/membrane_transport/membrane_transport.htm</p><p>2. Go through the tutorial. 3. What is cellular transport and why is it critical?</p><p>4. Click on “Membranes”. 5. What two characteristics of molecules do not allow them to pass through the membrane and why? </p><p>6. Click on the left side of the diagram. 7. How might a polar molecule like water pass through the membrane?</p><p>8. Click on “Diffusion/Osmosis”. 9. What causes non-polar molecules to move across the membrane? What is the driving force? 10. Use the continue button to advance through the animation.</p><p>11. Click on “Passive Transport”. 12. Click on the continue button to advance through the animation 13. What is the role of passive transporters?</p><p>14. Click on “Active Transport”. 15. What do active transporters do that is different from passive transporters? Part 2: 1. Go to: http://www.wisc-online.com/objects/index_tj.asp?objID=AP11003 2. Use the NEXT button to advance through the animation. 3. Why did the water go from side B to side A on the initial situation?</p><p>4. What do you think isotonic, hypertonic, and hypotonic mean? Why is each important in regards to cells?</p><p>Part 3: 1. Go to: http://programs.northlandcollege.edu/biology/Biology1111/animations/transport1.html 2. Click on Passive Transport. Use the next button to advance through the animation. 3. What makes up the cell membrane? Diagram the lipid bilayer.</p><p>4. What is diffusion? How does it relate to a concentration gradient?</p><p>5. What three things can affect the rate of diffusion?</p><p>6. How is facilitated diffusion different than normal diffusion? What macromolecule is involved? 7. When will osmosis occur and for how long?</p><p>8. How is active transport different than passive transport?</p><p>9. Diagram and explain the following forms of active transport: a. ION PUMPS – </p><p> b. COTRANSPORT – </p><p> c. ENDOCYTOSIS - </p>
