  8. True or False The plasma membrane controls the diffusion of water.

  9. False

  10. The movement of a substance from an area of high concentration to an area of low concentration.

  11. Diffusion

  12. The movement of a substance, that requires energy, against a concentration gradient

  13. Active Transport

  14. Transport of materials across the cell membrane by way of transport proteins.

  15. Facilitated Diffusion

  16. What are the 3 types of Passive Transport

  17. 1. Diffusion • Osmosis • 3. Facilitated Diffusion

  18. How many layers make up the cell membrane?

  19. 2

  20. What type of molecule makes up the cell membrane?

  21. Phospholipid

  22. What are the two ends of a lipid?

  23. 1. Hydrophilic (water loving) phosphate head 2. Hydrophobic (water fearing) fatty acid tail

  24. Term that describes how the cell membrane acts or works?

  25. Selectively Permeable

  26. Why is the cell membrane describes as the Fluid Mosaic Model?

  27. Fluid because the membrane is flexible & Mosaic because of the transport proteins stuck in it.

  28. What area around a cell called?

  29. Surface Area

  30. What is the area inside the cell?

  31. Volume

  32. The comparison between surface area and volume?

  33. Surface area to volume ratio

  34. As surface area increase what happens to volume?

  35. Increase

  36. Why are cells so small?

  37. So their membranes can stay small and things can diffuse across it quickly

  38. The diffusion of water is called?

  39. Osmosis

  40. If a cell is placed into a isotonic solution it is in a state of _________ _____________.

  41. Dynamic Equilibrium

  42. Identify the solution. 40% NaCl 60% H2O 22% H2O 78% NaCl

  43. Hypertonic 40% NaCl 60% H2O 22% H2O 78% NaCl Shrink

  44. Identify the solution. 20% NaCl 80% H2O 80% H2O 20% NaCl

  45. Isotonic 20% NaCl 80% H2O 80% H2O 20% NaCl Stay the Same

  46. Identify the solution. 78% NaCl 22% H2O 60% H2O 40% NaCl

  47. Hypotonic 78% NaCl 22% H2O 60% H2O 40% NaCl Swell

  48. Proteins responsible for moving materials through the plasma membrane are ?

  49. Transport or Channel Proteins
