    • TEKS 7.12F: Recognize that according to cell theory all organisms are composed of cells and cells carryon similar functions such as extracting energy from food to sustain life.Purpose: To learn about the scientists who contributed to the development of theCell Theory and to the rejection of spontaneous generation.TASK: You will use internet resources to create a timeline that begins with theinvention of the compound microscope to the experiment that finally dispelled theoutdated idea of spontaneous generation. After completing your timeline, you shouldsummarize the three parts of the cell theory in your own words. The Scientists (Include pictures in your timeline) 1) Zacharias Jansen 2) Anton van Leeuwenhoek 3) Robert Hooke 4) Matthias Schleiden
    • 5) Theodor Schwann 6) Rudolf Virchow7) Louis PasteurResearch the following questions about each scientist and include thisinformation in your timeline. * How did this scientist contribute to the cell theory? (Make sure the information that you provide here is related to the cell theory.) * When did this scientist make his contribution to the cell theory? * How did this scientists invention, idea, or experiment help lead to the rejection of spontaneous generation?

This theory was the generally believed to be thecomposed of cells and that an backbone for the cell theory weembryonic plant arose from a first investigator to invent the know today compound microscope.single cell.Louis Pasteurspontaneous generation ofmicroscopic animals.Pasteur boiledsome broth to kill any microbespresent. With special glassware, heallowed air to circulate over the broth,but prevented microbes in the airfrom reaching the broth. As Pasteurexpected, no microbes appeared inthe broth. Pasteur’s findings showedthat microbes were not spontaneouslygenerated from the broth itself.
