CELLS Page # 35

Cell History Robert Hooke 1665- ______________________ used a microscope to examine a thin slice of cork and saw “little boxes” He called them “CELLS” because they looked like the small rooms that monks lived in called Cells

Cell History Anton van Leeuwenhoek 1673- a Dutch microscope maker was the first to see LIVING ORGANISMS. Cell History Anton van Leeuwenhoek

Cell History 1838-Matthias Schleiden concluded that ALL PLANTS are made of cells. 1839-Theodore Schwann concluded that ALL ANIMALS are made of cells. 1855-Robert Virchow saw dividing cells in the microscope and reasoned that cells come from other cells.

The Cell Theory- 1. All living things are composed of cells. 2. Cells are the basic unit of structure and function in living things. 3. New cells are produced from existing cells.
