1. Chapter 5 Review Sheet

2. Type of transport where substances enter and leave the cell WITHOUT using energy ► Passive transport

3. Three types of passive transport: ► 1. diffusion ► 2. osmosis ► 3. facilitated diffusion

4. When molecules move from an area of high concentration to an area of low concentration ► diffusion

5. Three things that influence the rate of diffusion: ► 1. Temperature ► 2. Pressure ► 3. Concentration

6. When the concentration of molecules is the same throughout a solution ► equilibrium

7. Membranes that only allow certain molecules to pass through ► Semi-permeable

8. Diffusion of WATER ► osmosis

9. When the concentration inside the cell EQUALS the concentration outside the cell ► isotonic

10. When water enters the cell and it swells ► Hypotonic solution

11. When water leaves the cell causing it to shrink ► Hypertonic solution

12. Kind of pressure that keeps plant cells strong ► Turgor pressure

13. When the cell membranes of plant cells pull away from the cell wall when there is a shortage of water ► plasmolysis

14. Diffusion that uses proteins to help move particles across the cell membrane ► Facilitated diffusion

15. Molecules moving from an area of LOW concentration to an area of HIGH concentration ► Active transport

16. Does active concentration require energy from the cell? ► yes

17. Does passive transport require energy from the cell? ► no

18. Active transport where molecules are taken INTO the cell ► Endocytosis

19. Active transport where molecules are moved OUT of a cell ► exocytosis

20. Type of endocytosis that allows FLUIDS into a cell ► pinocytosis

21. Type of endocytosis that allows solids into the cell ► phagocytosis

22. The sodium potassium pump allows _______ molecules in and _______ molecules out ► Potassium ( K +) IN ► Sodium (Na +) OUT

23. Form of energy for the cell? ► ATP

24. Which cell structure maintains homeostasis? ► Cell membrane

25. ► What happens if a freshwater plant is placed in a salt water aquarium (2pts)?

26. ► Why could you smell the perfume when I sprayed it (2pts)?
