Presentation Transcript

  1. History of Cells • All living things are made of cells - the basic unit of structure and function of living things - “the building blocks of life”. • Scientists have studied cells for the last 300 years with the aid of microscopes.

  2. Robert Hooke (1665) • English scientist • Looked at a thin slice of cork through a compound microscope • Observed tiny, hollow roomlike structures • Called these “cells” because they reminded him of rooms that monks lived in • Only saw the outer walls (cell walls)

  3. Anton van Leeuwenhoek (1680) • Dutch scientist • examined pond scum, blood, rainwater, and scrapings from his teeth • observed tiny living things which he referred to as “animalcules” which means “little animals”. • These are known today as bacteria

  4. Matthias Schleiden (1838) • German botanist • Viewed plant parts under a microscope • discovered that all plant parts are made of cells

  5. Theodor Schwann (1839) • German zoologist • Viewed animal parts under a microscope • discovered that animal parts are made of cells.

  6. Rudolph Virchow (1858) • German physician • concluded that all living cells come only from other living cells

  7. The work of all of these scientists went into creating the cell theory. • All organisms are composed of one or more cells. • The cell is the basic unit of life in all living things. • All cells come from existing cells.
