Cell Transport STEM Activity 11/22/16
You will need:
- Biology Textbook - iPad - Headphones - Composition Notebook
Title the next page of your composition notebook Cell Transport Activity. Follow the instructions to complete the introductory activity on Cell Transport. Write the answers to the questions in your composition notebook. You do not need to write the questions.
1. Turn to page 208 in your textbook. Read the THINK ABOUT IT section at the top of the page.
What does the book compare the cell membrane to in the analogy?
2. Look at the bold print by the blue key on page 209. Define the term passive transport.
3. Go back to page 208 and find the word Diffusion in blue. Read this section. Answer the following questions:
A. What does the cytoplasm consist of?
B. How do particles tend to move?
C. What is the name given to this process?
D. What term is given to a solution when the concentration of substances is the same on both sides of a membrane?
4. Look down a the second half of page 209. Read this section and answer the following questions:
A. What type of molecule passes easily through the cell membrane?
B. Define the term facilitated diffusion.
C. From page 209, identify a molecule that moves through a membrane by facilitated transport.
D. Turn to page 210. Identify a second molecule that new research shows moves by facilitated diffusion.
E. Using Figure 7-16, draw a sketch to show this specialized protein. Label the cell membrane, the water, and the aquaporin in your diagram and give it a title..
5. Find the term osmosis in bold print on page 210. Define the term osmosis.
6. Read the paragraph at the bottom of page 210, and examine Figure 7-18. There are three types of conditions a cell can face- isotonic, hypertonic, and hypotonic. For each condition:
A. Define the condition.
B. Draw a simple picture of the cell (plant or animal) and use arrows to show the movement of water.
7. Watch the Amoeba Sisters video on Osmosis: A Solute and Solvent Love Story
Answer the questions:
A) What happens to a salt water fish if you put it in fresh water?
B) Explain why putting salt on a slug kills the slug.
8. Turn to page 212. Find the bolded words next to the blue key. Define the term active transport.
9. What does active transport require? (Use a one word answer.)
10. What carries out active transport of small molecules or ions across a cell membrane?
11. Identify 3 types of ions moved by the proteins pumps.
12. Look at Figure 7-19. Where does the energy to drive these pumps come from?
13. How do the pumps move the ions across the membrane?
14. Look at page 213. There are two types of bulk transport- endocytosis and exocytosis. Distinguish between endocytosis and exocytosis and draw a simple picture of each process.
15. Examine Figure 7-20. What is being taken into the white blood cell by mean of endocytosis?
16. Complete the Membrane Channels simulation from PhET.
1) Download and open the simulation.
2) Click the Show Concentrations box on the right.
3) Using the top red button on the left, add 30 green molecules to the top of the membrane.
4) Using the bottom red button on the left, add 30 blue molecules to the top of the membrane.
5) Notice the size of the green and blue bars on the bar graph on the right. This compares the concentrations of the green and blue molecules.
6) Click and drag a green gated channel and a blue gated channel up to the yellow membrane.
7) Open the channels by using the button on the top right.
8) Watch the bars in the bar graph.
Answer the questions:
A) What happened to the concentrations of the molecules after a few minutes?
B) Why could you have predicted this would happen?
