1. Cell Structure and Function Chapter 7

2. Cell Discovery-1
1. Robert Hooke (1665) - English Scientist that viewed the first cell from a thin slice of cork
He coined the term “cell” because the small units reminded him of monk cells in a monastery

3. Cell Discovery-2
2. Anton van Leeuwenhoek (1674) – Dutch businessman who made/improved microscopes, and is credited with seeing the first LIVING cells from pond water and blood
van Leeuwenhoek is sometimes referred to the “Father of Microbiology”

4. Cell Discovery - 3
3. Matthias Schleiden (1838) - German botanist who stated that all plants are made of cells
4. Theodore Schwann (1839) – German zoologist who stated that all animals are made of cells

5. Cell Discovery - 4
5. Rudolf Virchow (1855) – German doctor who proposed The Cell Theory
The Cell Theory has 3 parts:
A. All living things are composed of cells
B. The cell is the smallest unit of structure and function in an organism
C. New cells come from pre-existing cells*
The last part is what makes this a theory, because no one can prove where the 1st cell came from
