5. This nonpolar substance is composed of glycerol and fatty acids. It forms the “bilayer” of the membrane.

6. Phospholipids Back to Game Board

7. These molecules are found on the outer surface of the membrane and play a role in cell recognition and identification.

8. Carbohydrates Back to Game Board

9. This component of the membrane provides channels through which polar substances can cross the membrane.

10. Transport Proteins Back to Game Board

11. This term used to describe the cell membrane means that the membrane has control over what enters and leaves the cell. Some molecules are allowed to enter while others are not.

12. Selectively Permeable Back to Game Board

13. Term meaning that the cell maintains a balance through self regulating adjustment.

14. Homeostasis Back to Game Board

15. In the absence of other forces, molecules will tend to move from an area of _____ concentration to an area of ______ concentration.

16. High to Low Back to Game Board

17. What does the term “passive transport” mean?

18. Passive transport means that no energy is being used by the cell for the transport of that particular substance. Back to Game Board

19. Term used to describe the movement of water from an area of high concentration to an area of lower concentration.

20. Osmosis Back to Game Board

21. The movement of molecules (other than water) from a high to a low concentration.

22. Diffusion Back to Game Board

23. What happens to the movement of molecules when equilibrium has been reached on both sides of the membrane?

24. The movement of molecules never comes to a halt. Molecules will continue to move back and forth across the membrane, provided that no energy is expended to prevent it. Back to Game Board

25. When the concentration inside the cell is equal to the concentration on the outside of the cell, the cell is said to be _______ to its surrounding.

26. Isotonic Back to Game Board

27. The side of the membrane that is high in solute concentration and low in water concentration is called:

28. Hypertonic Back to Game Board

29. The side of the membrane that is low in solute concentration and high in water concentration is called?

30. Hypotonic Back to Game Board

31. This condition occurs if too much water leaves the cell and the cell collapses.

32. Plasmolysis Back to Game Board

33. This condition occurs if the cell gains too much water and the cell membrane is ruptured.

34. Cytolysis Back to Game Board

35. What does the term “active transport” mean?

36. Active transport means that energy is being exerted for the transport of a material across the membrane. Back to Game Board

37. The process by which the cell takes material into the cell by the infolding of the cell membrane.

38. Endocytosis Back to Game Board

39. The process by which the cell releases large amounts of material.

40. Exocytosis Back to Game Board

41. When extensions of the cytoplasm surround and engulf large particles and take them into the cell, it is known as?

42. Phagocytosis Back to Game Board

43. The process by which the cell takes in liquid from the surroundings is called?

44. pinocytosis Back to Game Board

45. These types of molecules may have trouble crossing the membrane and will need the help of transport proteins.

46. polar Back to Game Board

47. The process of moving specific molecules across cell membranes with the help of transport proteins is called?

48. Facilitated Diffusion Back to Game Board

49. Is facilitated diffusion considered active or passive transport?

50. Passive Back to Game Board

51. It is unlikely that a plant cell will undergo cytolysis. Explain.

52. As water enters the plant cell, the cell membrane is pushed against the cell wall. The cell wall supports the membrane and it is not likely that the membrane will rupture. Back to Game Board

53. As more and more water moves into a plant cell, there will be an increase in ________.

54. Turgor Pressure Back to Game Board
