  1. Cell History

  2. What is a cell? • The basic unit of living matter • All organisms are made of cells • Unicellular (bacteria, protists) • Multicellular (plants, animals)

  3. Types of Cells • Nerve Cell – long, thin, transmit electrical impulses • Muscle Cells – long, elastic, produce high amounts of energy

  4. Types of Cells • Skin Cells – interlocked like puzzle pieces and quick to reproduce • Fat Cells – do nothing but sit there and grow (storing fat)

  5. 6 minute rundown • http://www.youtube.com/watch?v=4OpBylwH9DU

  6. Key people in the development of cell theory • Anton Van Leeowenhook(1670-1680) • Developed first compound microscope • Robert Hooke (1660) • Coined the term “cell” while looking at a slice of cork • Named them cells because he thought they looked like prison cells

  7. Key people in the development of cell theory • Rene Durochet(1820) • Various parts of organisms are made of cells • Robert Brown (1830) • Cell has a large central part called a nucleus • Felix Dijarddin(1835) • Cells full of jelly-like fluid

  8. Key people in the development of cell theory • Mathias Schleiden (1838) • Botonist who said all plants and their parts are made of cells • Theodore Schwann (1838) • Zoologist who said all animals and their parts are made of cells • Rudolph Virchow (1858) • All cells must come from other cells

  9. Cell Theory • Schleiden, Schwann, and Virchow are credited with developing the … CELL THEORY • All living things are composed of cells. • Cells are the basic unit of life. • All cells come from pre-existing cells.

  10. Your Assignment • Create a timeline including all 8 scientists and their contribution to the history of the cell. • Draw a picture to help you remember what their contribution was • Must be in color 
