CELL THEORY AND DISCOVERY OF THE MICROSCOPE References: Heinemann Science Links VELS Edition Chapter 8 (pp 186 – 207). But don’t just rely on the textbook. You will need to consult some other references in the library on the web like: [|**http://library.thinkquesst.org/COO4535**] 1. Construct a timeline that charts the development of the microscope and the invention of the cell theory. Include the following scientists:

Jean Baptiste van Helmont Rene Dutrochet Francesco Redi Lazzaro Spallanzani Louis Pasteur Hans Jansen Zacharias Jansen Robert Hooke Anton van Leeuwenhoek Matthias Schleiden Theodor Schwann Rudolf Virchow Ernst Ruska

2. What connection can you describe between the invention of the cell theory and the development of the microscope? Do you think that our knowledge of cells would have developed without the microscope?

3. What was the theory of spontaneous generation? Whose idea was it? Why did he believe it? Who disproved this theory? How?

4. Describe and explain the Cell Theory.

5. Choose one of the scientists from the list above and describe their life and work. Include things like where and when they were born and died, some details about their family life and information about their scientific discoveries.

6. Sir Isaac Newton is said to have claimed that he had been so successful because he had been able to stand on the shoulders of giants. By this we think he meant that by using the work of other scientists he was able to make his own discoveries. Do you think that the development of the microscope and the creation of the cell theory support this idea. This is a “fat” question. You will need to work out what Newton meant first before you can decide if this an example to support his thoughts.
