Cell Discovery and Theory Chapter 7-1 The wacky history of cell theory - Lauren Royal-Woods –

I. Discovery Mid 1600’s

A. Robert Hooke (1665) Looked at cork and saw tiny little boxes Reminded him of rooms in a monastery Called the “little rooms” CELLS

B. Anton Van Leeuwenhoek (1674) First person to use microscope to identify LIVING things Reminded him of “little animals” Named them animalcules

C. Matthias Schleiden (1838) Botanist Concluded all plants are made of cells

D. Theodor Schwann (1839) Zoologist Concluded all animals are made of cells

E. Rudolph Virchow (1855) Virologist Concluded that CELLS COME FROM PRE-EXISTING CELLS

F. Cell Theory (Based on findings from 5 scientists) All living things are composed of cells Cells are the basic unit of structure and function in living things New cells are produced from pre-existing cells

II. All cells have Cell membranes Genetic Info (DNA/Chromosomes)

III. Two Category of cells- Depending on if they have a nucleus Eukaryotic cells - contain nucleus Prokaryotic Cells- Do NOT contain nucleus

A. Prokaryotic Cells (Bacteria) Smaller and simpler than eukaryotic cells DNA not inside a nucleus-instead floats in cytoplasm 2 of 6 KINGDOMS are prokaryotic Archaebacteria and Eubacteria.

B. Eukaryotic Cells (everything except bacteria) Larger and more complex DNA inside nucleus 4 of 6 KINGDOMS are eukaryotic Plant, animal, fungi and protist
