  1. TOPIC: Cells AIM: Describe the cell theory. Do Now: Measurement Review (Take out yesterday’s notes) HW: 4 ?’s on bottom of microscopic measurement sheet

  2. 1. The amount of matter an object has is called • mass (2) volume (3) milliliters (4) density 2. The SI unit of mass is the ______. • cubic meter (2) kilogram (3) liter (4) meter

  3. 3. In the metric system, the height of a building would be given in • centimeters (2) milliliters (3) meters (4) millimeters

  4. 4. Which instrument would be used to obtain the volume of a glass of water? • triple beam balance (2) graduated cylinder (3) beaker (4) metric ruler

  5. 5. An object has a length of 2 cm, a width of 3 cm, and a height of 4 cm. What is it’s volume? • 11 cm3 (2) 26 cm3 (3) 9 cm3 (4) 24 cm3

  6. 6. Which measurement of an average classroom door is closest to 1 meter? • its thickness • its width • its height

  7. The basic unit of length in the metric system is the • kilogram • gallon • liter • meter

  8. Carrie is working with a graduated cylinder as shown in the diagram. What should Carrie do to get a volume of 12.5 milliliters (mL) of liquid in the graduated cylinder? • Add 0.5 mL of liquid • Add 1.5 mL of liquid • Remove 0.5 mL of liquid • Remove 1.5 mL of liquid

  9. Which pieces of laboratory equipment could be used in the laboratory to measure density? 1. A and B 2. B and D 3. B and C 4. B and D

  10. The diagram represents a thermometer. The temperature reading on the thermometer would most likely indicate the temperature • of a human body on a very hot summer day • at which water freezes • at which water boils • of a human with a very high fever

  11. The diagram shows equal masses of four different earth materials at different temperatures. Which material has the greatest density? 1. water 2. iron 3. granite 4. dry air .00012 g/cm3 2.7g/cm3 1.0 g/cm3 7.7 g/cm3

  12. Excretion • Removal of cellular (metabolic) waste

  13. Locomotion • Ability of an organism to move

  14. Factors that influence metabolism • Gender • Age

  15. Exercise • Diet • Drugs and alcohol

  16. Carry out life processes Make up living things (ORGANISMS) Cells

  17. Just like bricks make up a brick house, cells make up an organism

  18. The Cell Theory – a timeline Robert Hooke ( 1665)

  19. 1. Cells are the basic unit of structure in all living things. (Living things are made of cells) Cell Theory

  20. 2. Cells are the basic unit of function of all living things (They carry out life processes) 3. All cells come from pre-existing cells.

  21. Viruses: not composed of cells contain genetic information reproduce inside host cell Exceptions to the Cell Theory

  22. Virus do not reproduce by division because they are not cells.

  23. Didyou know… • The first virus was found in both plants and animals 100 years ago. • The common cold is a type of virus. • Viruses can be treated with antiviral drugs.

  24. Let’s summarize… • What do all organisms consist of? • Explain the three parts of the cell theory. • Explain why viruses are exceptions to the cell theory.

  25. Review: • Which statement is not a part of the cell theory? • Cells are the basic unit of structure of living things. • Cells are the basic unit of function of living things. • Cell parts such as chloroplasts are self-replicating. • Cells come from preexisting cells.

  26. 2. The cell theory states that all living things are made up of • organisms 2. cells 3. tissues 4. proteins

  27. 3. Which choice is NOT part of cell theory? • Cells are the basic units of life. • All living things are made of one or more cells. • All cells come from other living cells. • New cells have the same nuclei as those of pre-existing cells.
