  1. Cells Cells

  2. Cells are produced from nonliving things Which statement is NOT part of cell theory? • A. Cells can be produced from other cells. • B. Cells are produced from nonliving things. • C. All living things are made of cells.

  3. How sharp an image is What does the term resolution refer to? • A. How sharp an image is • B. How big an image can be • C. To make an object bigger • D. How much light is needed to make an object

  4. Uses electrons to create an image In an electron microscope how does magnification occur? • A. Convex lens bend light to make objects look bigger • B. The convex and concave lens bend to make the objects look bigger. • C. Light is reflected by a electron beam • D. Uses electrons to create an image

  5. 40 • What is the total magnification of a microscope when one lens is 10 and the other is 4?

  6. Convex lens bend light to make objects look bigger How does the lens of a light microscope work? • A. Convex lens bend light to make objects look bigger • B. The convex and concave lens bend to make the objects look bigger. • C. The reflection of each lens make the object look bigger.

  7. Cells are alive Anton Von Leewenhoek observed that cells: • A. have a cell wall • B. Cells are alive • C. Could be seen by an electron microscope • D. Could be seen by a light microscope

  8. Make objects look bigger Magnification is • A. Make objects look bigger • B. Make objects look smaller • C. Adds light to the object

  9. Found in all cells The cell membrane is: • A. Found in plant cells • B. produces energy for the cell • C. Found in all cells • D. Protects and supports the cell

  10. Cells The invention made it possible for people to discover • A. People • B. Skin • C. Animals • D. Cells

  11. Observation Using one or more of your senses to gather information is called: • A. Inference • B. Hypothesis • C. Prediction • D. Observation

  12. Inference Explaining or interpreting the things you observe from what you already know • A. Hypothesis • B. Prediction • C. Inference • D. Observation

  13. Observation Using one or more of your senses is: • Hypothesis • B. Prediction • C. Inference • D. Observation

  14. Data table An organized way to collect and record scientific observations is with a • A. Model • B. Definition • C. Data table • D. Inference

  15. Quantitative observation An observation that deals with numbers • A. Inference • B.Qualitative observation • C.Quantitative observation

  16. Hypothesis A possible explanation or set of observations • A. Hypothesis • B. Prediction • C. Inference • D. Observation

  17. Prediction Telling what will happen in the future based on past experience and evidence • A. Hypothesis • B. Prediction • C. Inference • D. Observation

  18. Graph A tool to help a scientist interpret data by revealing unexpected patterns: • A. Data table • B. Graph • C. Theory • D. Question

  19. Qualitative observations An observation that cannot be expressed in numbers. • A. Inference • B.Qualitative observation • C.Quantitative observation

  20. Dependent Variable The fact that may change in response to the independent variable is called: • A. Hypothesis • B. Independent Variable (Manipulated) • C. Dependent Variable (Responding) • D. Inference

  21. Independent Variable The variable that is being changed • A. Hypothesis • B. Independent Variable (Manipulated) • C. Dependent Variable (Responding) • D. Inference

  22. Nucleus The control center of the cell is the : • A. Mitochondria • B. Cell Wall • C. Nucleus • D. Nuclear envelope

  23. Cell Membrane Controls what comes in and out of the cell. • A. Cell Wall • B. Cell Membrane • C. Nucleus • D. Endoplasmic Reticulum

  24. Cell Wall Found in only plant cells. It protects and supports the cell. • A. Cell Wall • B. Cell Membrane • C. Nucleus • D. Endoplasmic Reticulum

  25. Vacuoles Stores food and other materials needed by the cell. • A. Ribosomes • B. Lysosomes • C. Vacuoles • D. Endoplasmic Reticulum

  26. Lysosomes Releases chemicals that break down large food particles into smaller ones. • A. Ribosomes • B. Lysosomes • C. Vacuoles • D. Endoplasmic Reticulum
