Zacharias Janssen Invents the first Microscope
Zacharias Janssen was a Dutch eyeglass maker. One day, he decided to experiment and put a concave lens on one side of a cylindrical tube and put a convex lens on the other side. The result could magnify specimens up to nine times its original size. Without his invention, we wouldn’t have ever discovered cells. -
Zacharias Janssen Continued
Zacharias Janssen’s work contributed to the rejection of spontaneous regeneration because when we study an inanimate object over time up close we see that living things don’t grow off of inanimate objects. -
Robert Hooke Names Cells
Robert Hooke, an English physicist, had published a book containing a description of cells. In one of Hooke’s experiments, he cut a sheet of cork (contains dead pant cells) and observed it under his custom microscope. He noticed that it was made up of what looked like boxlike monastery cells, which is where the name comes from. -
Robert Hooke Continued
Robert Hooke contributed the name of cells to the cell theory. Naming cells its given name let scientists specify what they meant when arguing about the of spontaneous regeneration. -
Anton van Leeuwenhoek gives the First Description of Living Cells
Dutch scientist Anton van Leeuwenhoek had been studying living Bacteria and Protozoa under a microscope. He later because the first person to give a description on livings cells. Eventually, Leeuwenhoek discovered blood cells, spermatozoa, and animacules. Without him, we wouldn’t have a basic understanding of what a cell is. -
Anton van Leeuwenhoek Continued
Leeuwenhoek’s work contributed to the rejection of spontaneous regeneration because since we have a basic understanding of what a cell is, we know that it can’t grow off of inanimate objects. -
Matthias J. Schleiden and Theodor Schwann invent the cell theory
German scientists Matthias J. Schleiden and Theodor Schwann, during an investigation, stated that cells were the building blocks of life, also known as the cell theory. Their work contributed the the cell theory by creating the cell theory. Their research contributed to the rejection of spontaneous regeneration because Schleiden and Schwann stated that a CELL is what forms and shapes life. That concludes that organisms can’t form off of inanimate objects. -
Rudolf Virchow Discovers Cell Regeneration
Rudolf Virchow was a German Scientist who discovered that every cell has to come from previously existing cells, which can also be described as cellular regeneration. His research contributed to the cell theory being that Theodor Schwann and Matthias Schleiden realized that cells are the building blocks of life, and Virchow discovered that they are also EACH OTHER’S building blocks. -
Rudolf Virchow Continued
Virchow’s work contributed to the rejection of spontaneous regeneration because Virchow had realized that cells come from previous cells, and the theory of spontaneous regeneration was that dead objects could spawn living things. If there were no cells already existing on top of the dead object, there can be no cells there in the first place, and since cells form life, that means that there can be no living object spawning from the dead object. -
