37. CELLS Back to Contents

38. What are Levels of organization from cells to organism? 1.Cells 2.Tissues 3.Organs 4.Organisms 5.Population 6.Community

39. What are the 2 types of Cells? Somatic (body cells) Gametes (sex cells)

40. Eukaryote cells vs Prokaryote cells Eukaryotic cellsProkaryotic cells Have nucleus Membrane-bound organelles Cell membrane DNA Liquid cytoplasm Ribosomes Some have cell walls Complex Both unicellular and multicellular Cell membrane DNA Liquid cytoplasm Ribosomes cell walls Simple Unicellular

41. Animal vs. Plant cell Animal cellsPlant cells Nucleus Cytoplasm Ribosomes Golgi body Mitochondrion Cell membrane Vacuole (smaller in animal cell) Endoplasmic reticulum Lysosomes (not in plant) Centrioles (not in plant) Nucleus Cytoplasm Ribosomes Golgi body Mitochondrion Cell membrane Vacuole (larger in plant cell than animal) Chloroplast (not in animal) Cell wall (not in animal) Endoplasmic reticulum

42. Nucleus Brain of cell

43. Cytoplasm Liquid substance in cell that holds organelles

44. Ribosomes Protein producers. They can be attached to the ER

45. Golgi Body External delivery system

46. Mitochondrion Convert energy in food molecules to energy the cell can use to carry out its functions

47. Cell membrane Regulates what goes in and out of the cell

48. Vacuole Storage areas of a cell. Huge in plant cell.

49. Chloroplasts Capture energy from sunlight and use it to produce food. (plant only)

50. Cell wall Stiff wall surrounding membrane. (plant only)

51. Endoplasmic Reticulum Internal delivery system

52. lysosomes Contain chemicals to break down food particles and worn out cell parts. (animals only)

53. Centrioles Help with cell division. (animals only)

54. What is diffusion Movement of molecules from areas of high to low concentration

55. What is osmosis Diffusion of water across a semi- permeable membrane

56. What is active transport Movement of molecules across a membrane using cellular energy. Often against concentration gradient

57. photosynthesis The process by which a cell captures energy in sunlight in order to make food

58. Respiration Process by which cells obtain energy from glucose

59. SCIENTIFIC METHOD Back to Contents

60. What are the steps of the scientific method? 1.Research 2.Problem Question 3.Hypothesis 4.Develop your Procedure 5.Collect and Record Data 6.Analyze Results 7.Draw Conclusions

61. Independent Variable The variable that you control

62. Dependent Variable Changes because of the Independent Variable

63. Experimental Group Tested Group

64. Control Group The group used for comparison

65. Control(s) What is kept constant throughout the experiment

66. Research Look up information to develop your hypothesis

67. Purpose/Proble m Question The purpose of the experiment

68. Hypothesis A statement that tells what you think is going to happen

69. Procedure Decide how you are going to do your experiment

70. Collect and record data When you do the experiment and you collect and record data

71. Analyze Results Translate your data into words

72. Draw Conclusions -Was your hypothesis correct?(y/n) -Why?(…) -What would you do differently next time? -What possible errors? -etc.
