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

10 What is the cell membrane?

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

12 What is diffusion?

13 State that exists whenever molecular concentration is the same throughout a space or across a membrane

14 What is equilibrium?

15 Solution type when solute concentrations inside and outside the cell are equal Solution type when solute concentrations inside and outside the cell are equal

16 What is isotonic?

17 Organelle in paramecia that pumps out excess water

18 What is a contractile vacuole?

19 Universal Solvent

20 What is water?

21 Chemical property that makes water such a good solvent

22 What is polarity?

23 External solution that causes water to move into the cell

24 What is hypotonic?

25 Direction water moves in passive transport

26 What is down the concentration gradient?

27 Prefix that refers to a high solute concentration compared to another solution

28 What is hyper-?

29 diffusion through a transport protein

30 What is facilitated diffusion?

31 Proteins that move substances across a membrane

32 What are transport or carrier proteins?

33 Direction across the cell membrane that carrier proteins allow movement

34 What is from higher to lower concentration?

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

36 What is change shape?

37 Type of molecules that cross by facilitated diffusion

38 What are amino acids or glucose? (polar or charged)

39 Passive transport without help of proteins

40 What is diffusion?

41 Direction molecules diffuse across a cell membrane

42 What is high to low concentration?

43 Water movement across a cell membrane

44 What is osmosis?

45 Point where molecules are evenly distributed

46 What is equilibrium?

47 Water pressure exerted against plant cell walls

48 What is turgor?

49 Required by cells when materials move by active transport

50 What is ATP or energy?

51 Direction of movement across a membrane during active transport

52 What is low to high concentration?

53 membrane “pumps” membrane “pumps”

54 What are transport proteins?

55 Membrane pumping system that keeps Na+ ions concentrated

56 What is the sodium- potassium pump?

57

58 Process where cells “drink” droplets of liquid

59 What is pinocytosis?

60 Condition inside cell if outside of cell is hypotonic

61 What is hypertonic?

62 A unicellular organism’s organelle which pumps out water

63 What is a contractile vacuole?

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

65 What is water moving into the cell?

66 Molecules soluble in this can diffuse through the cell membrane

67 What are lipids?

68 Condition inside cells when plant cells lose turgor pressure and wilt

69 What is plasmolysis?

70

71 Transport

72 Kinetic energy of molecules or a concentration gradient

73 What makes passive transport possible?
