  1. EQ: How was the cell theory developed? Do-Now: Use pages 69-72 to answer the following question. Are all cells exactly alike? Why or why not? Be prepared to defend your answer.

  2. Introduction to Cells

  3. 1665-Robert HOOKE saw the cell walls of cork and called them “CELLS” Discovery of the cell

  4. 1673 Anton van LEEUWENHOEK saw the first living cells in a drop of water – “little animals”

  5. 3 Discoveries that led to the Cell Theory • 1838 Matthias SCHLEIDEN concluded all plants were composed of cells • 1839 Theodor SCHWANN concluded all animals were composed of cells • 1855 Rudolf VIRCHOW observed cell division.

  6. The Cell Theory (3 parts) • All living things are composed of cells • Cells are the basic units of structure and function in an organism • Cells come only from the reproduction of existing cells

  7. Cell Diversity • Not all cells are alike • Sizes and shapes vary for structure and function

  8. 1/11/12 • Do-Now: Complete the GRECHO warm up on the back of your Cell Theory Notes from Yesterday. • We have discussed 5 scientists so far. List their names & what they did. • List the 3 parts of the cell theory. →notebook, paper, pencil • Finish Intro to Cells; p169, 7-1 Vocabulary • Cell Theory Quiz • Pretest; Cell Structure & Function Tree Map (174-183

  9. Cells contain a variety of internal structures called ORGANELLES. ORGANELLE –a cell component that performs specific functions for the cell

  10. The 2 main types of cells: • PROKARYOTES-cells without a nucleus or membrane-bound organelles, have circular genetic material • Bacteria are the ONLY examples

  11. EUKARYOTES – cells that have a nucleus and membrane bound organelles. Plants, animals, protists & fungi are examples Types of cells, cont.

  12. Ticket to Leave • Who were the three scientists to develop the cell theory? • What are the three parts of the cell theory? • What are the two main types of cells?

  13. 8/12/11 • Do-Now: Have out the “Prefix/Suffix/Root vocabulary on your desk. • Contrast prokaryotes & eukaryotes. List an example of each. • What do the following prefixes/suffixes/roots mean? • Uni- b. Multi- c. Pro- d. Eu- e. Auto- f. Hetero- g.
