Hooke discovered cells
While observing a slice of cork under a microscope, Hooke, discovered small honeycomb like structures. He called each individual one a "Cell". This started the chain of discoveries. -
Leeuwenhoek sees living cells
While observing a sample of pond water, he noticed small cells moving and interacting. These were amoung the first living cells observed. Leeuwenhoek also discovered the first bacterial cells. This not only added to Hookes statement that cells makeup all matter, but it also set the foundation for more discoveries. -
Brown sees plant nucli
Brown was studying the epidermis of an orchid when he noticed that at the center of the cells there was a small opaque spot (the nucleus). This added to the previous thought that cells were present in all mater. -
Schlieden sees cells in plant tissues
Schleiden discovered that all plant tissues he examined with a microscope were composed of cells. He was the first to make a general statement about them in saying that all parts were composed of cells, in plants that is. He expanded on the statement before him by adding all plants in his statement. -
Shwann adds to the cell therory
While looking under a microscope at a tapole egg, Schwann identified small blocks of material. He proved that cell nuclei were present in more than plants but also animals. -
Virchow states cellular reproduction therories
Virchow’s theory stated that cells are unable to be produce without previously existing cells, like animals. The idea that new cells were from pre-existing cells was not original, but he was the first to prove it by -
