Unformatted text preview: Answers 1. What theory did these scientists provide evidence for? *the cell theory 2. What instrument was necessary before the cell theory could be developed? *The microscope 3. Which three scientists directly contributed evidence for the cell theory? *Matthias Schleiden, Theodor Schwann, Rudolph Virchow 4. How did the earlier scientists and their contributions directly affect the discoveries of later scientists (see #2)? For example, what had to come first? *Hans and Zacharias Janssen had to first develop the microscope before cells could be discovered. Robert Hooke then discovered empty, dead cork cells in tree bark. Anton van Leeuwenhoek discovered the existence of living cells and is sometimes given credit for the microscope. 5. List the three parts of the cell theory. *All living things are made of cells. *Cells are the basic units of structure and function in living things. *Living cells come only from other living cells http://www.usoe.k12.ut.us/curr/science/sciber00/7th/cells/sciber/sample.htm Timelines New Phytologist (2004) 163 : 14 www.newphytologist.org Forum 7 Levin SA, Durrett R. 1996.

Timelines The birth of cell biology 18041881: the bicentenary of the birth of Matthias Jakob Schleiden Matthias Schleiden was, along with Theodore Schwann, one of the formulators of the classical cell theory of organism structure. Schleiden had a complex life: his belief that he had failed in his first career as a barrister led him to attempt suicide by shooting himself in the head. After recovering, he re-trained as a scientist. Whilst this could be construed to mean one needs a complete brain even to fail as a lawyer but...
