  5. Robert Hooke Anton van Leeuwenhoek Matthias Schleiden Theodore Schwann Rudolf Virchow began using microscopes and gave the cell its name (bark/cork). described the living cell. studied cellular transport in plants and that the nucleus is important in cell division. looked at animals and concluded that all animals are made of cells as well. cells come from other living cells. New Characters

  6. Cell Theory • Every living thing is made of one or more cells. • Cells carry out the functions needed to support life. • Cells come only from other living cells. http://my.hrw.com/sh2/sh07_10/student/flash/visual_concepts/60048.htm

  7. Spontaneous Generation

  8. Bacteria and Spontaneous Generation • Microorganisms are everywhere. • Understanding microorganisms (germs) help scientists learn how to prevent diseases. • Some scientists thought bacteria grew from nonliving materials, an idea called spontaneous generation.
