10. 9 Helps an organism maintain homeostasis by controlling what enters or leaves the cell

11. 10 What is the cell membrane?

12. 11 Causes the concentration of molecules to be the same throughout a space

13. 12 What is diffusion?

14. 13 State that exists whenever molecular concentration is the same throughout a space

15. 14 What is equilibrium?

16. 15 When the concentration of solutes inside & outside the cells is equal

17. 16 What is isotonic?

18. 17 Organelle in paramecia that pumps out excess water

19. 18 What is a contractile vacuole?

20. 19 Universal Solvent

21. 20 What is water?

22. 21 Property that makes water such a good solvent

23. 22 What is polarity?

24. 23 Solute concentration that causes water to move into the cell

25. 24 What is hypotonic?

26. 25 Direction water moves in passive transport

27. 26 What is down the concentration gradient?

28. 27 Prefix that refers to a high solute concentration & low water concentration outside the cell

29. 28 What is hyper-?

30. 29 Facilitated diffusion is another example of this type of transport

31. 30 What is passive?

32. 31 Proteins that aid facilitated diffusion

33. 32 What are carrier proteins?

34. 33 Direction across the cell membrane that carrier proteins allow movement

35. 34 What is higher to lower?

36. 35 This happens to a carrier molecule when it binds with the molecule it’s moving

37. 36 What is change shape?

38. 37 Type of molecules that move by facilitated diffusion

39. 38 What are amino acids or glucose?

40. 39 Simplest type of passive transport

41. 40 What is diffusion?

42. 41 Direction molecules diffuse across a cell membrane

43. 42 What is high to low concentration?

44. 43 Water movement across a cell membrane

45. 44 What is osmosis?

46. 45 Point where molecules continue to move without a concentration gradient

47. 46 What is equilibrium?

48. 47 Water pressure exerted against plant cell walls

49. 48 What is turgor?

50. 49 Required by cells to move materials by active transport

51. 50 What is ATP or energy?

52. 51 Direction of Movement across a membrane during active transport

53. 52 What is low to high concentration?

54. 53 Act as cell membrane “pumps”

60. 59 What is pinocytosis?

61. 60 Condition of the cytosol if the outside of the cell is hypotonic

62. 61 What is hypertonic?

63. 62 A multicellular organism’s response to being in a hypotonic solution

64. 63 What is pumping out solutes?

65. 64 Direction of water movement when the solute concentration outside the cell is lower than inside

66. 65 What is water moving into the cell?

67. 66 Molecules soluble in this can diffuse through the cell membrane

68. 67 What are lipids?

69. 68 Condition caused whenever plant cells lose turgor pressure and wilt
