Summaries on Cell Theory and Organization of multicellular organisms required.
 * __Discovering Cells__**(Cornell Style)

1. All living things are made of cells. 2. Structure is how something is made. 3. Function means what something does. 4. Cells are the basic units of structure and function in living things. 5. All the functions of living things occurs in cells. 6. Cells function similarly in all organisms. 7. Cells are so small they are measured with units that are 1000th of a millimeter. 8. The invention of the microscope and its improvement made it possible for people to learn about cells. 9. Robert Hooke and (LAY vun hook) Anton van Leeunenoek both built their own microscopes and studied cells. 10. Robert Hooke saw empty spaces in cork and called them cells. 11. Anton van Leeunhoek found microscopic organisms in water and describes parts of the cell. 12. Cell theory: a. All living things are made of cells b. Cells are the basic units of structure and function in living things c. All cells are produced from other cells 13. Cell Theory was developed over time from many microscopic observations. 14. Unicellular – single celled organisms like bacteria 15. Multicellular – organisms composed of many cells 16. Levels of organization in organisms. A. Tissue – a group of similar cells that work together at one function/job B. Organ- a structure with a function that is made of more than one tissues C. Organ system – a group of organs that work together to perform a major function of the body.

Summary writing prompts: Paragraph 1: Cell Theory was developed over time from many microscopic observations. See note 12 above for the facts to include. Paragraph 2: Tissues, organs, and organ systems are the three levels of cell organization in multicellular organisms. See note 16 above for the facts to include. finish each paragraph with a concluding sentence.
