7.1 Notes: Discovery and cell theory The Cell 7.1 Notes: Discovery and cell theory

How did we discover cells? -Microscope development led to new discoveries.

Year 1665 1683 1880-1890 1839 1939 1970 Name Robert Hook Anton van   Year 1665  1683 1880-1890 1839 1939  1970 Name Robert Hook  Anton van Leeuwenhoek  Louis Pasteur & Robert Koch Theodore Schwann Earnest Everett Just  Lynn Margulis  Description Of Discovery Observecook and calls it cells  Discovers single-celled animal like organism  All plants are made of cells.  Tissue of all animals have cells States all cells come from existing cells  some organelles found in Eukaryote were once in Prokaryote

Characteristic of living organisms The CELL is the basic unit of LIFE

The Cell Theory Scientist Responsible for: Schleiden-Plants Schwann-Animals Virchow-New cells from existing cells

All living things are composed of cells. THE CELL THEORY All living things are composed of cells. Cells are the basic units of structure and function in living things. New cells are produced from existing cells.

Prokaryote vs. eukaryote -PRO= Before -EU= True Prokaryotes do NOT have a nucleus Eukaryotes HAVE a nucleus
