1. Cell Transport
Practice quiz

2. What are the key characteristics of Passive transport?

3. answer No Energy is used.
Movement goes from high --> Low Concentration.
answer

4. What is diffusion?

5. Diffusion is a type of passive transport where particles move from high concentration to low concentration.
Examples:
Puff of perfume
Smell of a camp fire
These particles diffuse throughout the room/area.
Answer

6. What things can diffuse through a cell cell membrane without the use of a protein?

7. Small and Uncharged molecules
Answer

8. What things can’t go through a cell membrane without the use of a protein?

9. Large and Charged Molecules.
Answer

10. What direction will the solute move?

11. Right, Down the Concentration gradient.
Answer

12. What direction will the water move?

13. Left, Down the Concentration gradient.
Answer

14. What is Osmosis?

15. The Diffusion of water across the cell membrane or through auqaporins.
Answer

16. Draw a picture to represent Hypotonic, hypertonic, and Isotonic solutions.

18. Fill out the chart on the next slide.

19. Type of Solution
Particle concentration
in solution
in cytoplasm
Where is there more water?
Which way will water move?
Hypotonic
Hypertonic
Isotonic

20. Type of Solution
Particle concentration
in solution
in cytoplasm
Where is there more water?
Which way will water move?
Hypotonic
Low
High
Outside
Inside
Hypertonic
Isotonic =
In and out Equally.

21. What is Facilitated Diffusion?

22. Answer A type of Diffusion that uses a protein. No energy needed.
High  Low Concentration.
Answer

23. What are the key points of Active Transport?

24. Answer Uses Energy (ATP)
Low --> High Concentration (against the concentration gradient)
Answer

25. Give an example of active transport.

26. Sodium Potassium Pump
Answer:

27. What are the two forms of transport for the “big” stuff?

28. Answer Endocytosis – When lots of stuff exits the cell
Exocytosis – when lots of stuff enters the cell.
