Development of the Cell TheoryHooke

1. 1663 used compound microscope to observe cork slices.2. Cork reminded him of rooms where monks lived.3. Thus, coined term “Cell”.

1. 1683 Used a simple microscope to observe pond water; “animalcules”2. First to observe bacteria (from his own teeth scrapings!)

Schleiden

1. “Botanist” who studied plants at a German university2. In 1838 said, “All plants are made up of cells.”

Schwann

1. studied frog larvae (animals) at same German university as Schleiden2. 1839 concluded “All animals are made up of cells.”

Virchow

1. Studied how a cell reproduces2. 1855 stated, “All cells come from pre-existing cells.”

Cell Theory

1. All living things are made up of cells.2. Cells are the basic unit of structure and function.3. All cells come from other cells.
