Zacharias and Hans Janssen invent the first microscope, which was slightly blurry
-
Hooke looks at a cork through a microscope and observes pores which he called cells.
-
A scientist named Redi performs an experiment with rotting meat to see if cells can come from dead things. His results showed that the theory of spontaneous generation was false.
-
Anton van Leeuwenhoek developed a simple microscope which he used to magnify up to 270x
-
Leeuwenhoek uses his microscope to observe yeast, water, and blood.
-
Leeuwenhoek shows his detailed pictures to the royal society.
-
A german scientist named Wolff creates a general cell theory.
-
Robert Brown observes the part found in cells that other people had seen before and gives it the name nucleus
-
Brown observes the nucleus he found in plant cells.
-
Matthias Jakob Schleiden finds that all plant tissues are composed of cells, he states that cells are the basic building block of plant matter. This develops the first part of the cell theory.
-
Theodor Schwann comes to the same conclusion as Schleiden for animals cells, in which all animal tissues are composed of cells. He creates the second part of the cell theory by saying that cells are the basic unit of life.
-
Remak demonstrates how cells divide to form new cells, proving that cells only come from other living cells.
-
Rudolf Virchow adds a third part to the cell theory by looking at observations of other scientists: All cells develop from other cells.
-
Similar to Redi, he proved spontaneous generation false when he replaced it with Biogenesis. This states that cells come from preexisting cells using information from the germ theory.
-
Scientist Camillo Golgi observes a nervous system and finds the organelle now called golgi bodies after being named after him
