Name: _______________________________ Class: _________ Date:____________ Cell Transport Web Quest For this web quest, use a computer to search the following websites and answer the corresponding questions. Link #1 – Pearson Lab Bench Activity: Diffusion and Osmosis https://tinyurl.com/moodylink1 Explore this website, read about and watch animations for key concepts 1 through 5. (Links to key concepts are found on the left hand side of the page.) Link #2 – McGraw Hill Animation: How Diffusion Works http://novella.mhhe.com/sites/0042561336/student_view0/chapter3/how_diffusion_works.html If prompted, click to run adobe flash, then allow it to run. If you have headphones, plug them in. Otherwise, simply read the text and watch the animation video. Then answer the following questions and take the quiz. 1. Describe what happens to moving molecules within a solution. 2. In terms of molecules, explain what happens to a sugar cube when it is placed into a beaker of water. 3. Define diffusion. 4. Using the arrow seen below, illustrate the diffusion of molecules from high concentration to low concentration. 5. What can affect the rate of diffusion? 6. Predict: what would happen if you drop the sugar cube into a beaker of hot water vs. a beaker of cold water. Link #3 – McGraw Hill Animation: How Osmosis Works http://novella.mhhe.com/sites/0042561336/student_view0/chapter3/how_osmosis_works.html Watch the animation video and answer the questions, then take the quiz. 1. Why can water pass through the membrane? 2. Where does the water move? 3. Explain the difference between hypertonic and hypotonic. 4. Take the quiz. What was your score? _________________ Link #4 – BBC Diffusion and Osmosis Activity https://tinyurl.com/moodylink4 Watch the interactive video (under the “Activity” tab) and answer the following questions. 1. When does diffusion occur? 2. Why does the ink spread out? 3. Why does the smoke spread out? 4. How does oxygen reach the blood? 5. What moves during osmosis? 6. What direction does the water move? 7. How does water get into plant cells? Link #5 – Diffen: Diffusion and Osmosis https://tinyurl.com/moodylink5 Read and use the information to create a Venn diagram. Link #6 – Stephen Murray Online Quiz: Osmosis and Diffusion https://tinyurl.com/moodylink6 Take the quiz. What was your score? _________________ Link #7 – Science Book: Passive and Active Transport http://www.sciencebook.dkonline.com/62.html Watch the animation called “Art in Motion: Passive and Active Transport” and answer the following questions. 1. What is passive transport? 2. What are two types of passive transport? 3. How do small molecules, such as oxygen (O2) or water (H2O) pass through the cell membrane? 4. What is active transport?
