He set up two experiments. In both, Pasteur added nutrient broth to flasks, bent the necks of the flasks into S shapes, and then boiled the broth to kill any existing microbes.]]> 2019-02-08 13:28:31 UTC https://padlet.com/kianapagan319/7s5jtayamsug/wish/329175379 https://padlet.com/kianapagan319/7s5jtayamsug/wish/329175784 With an electron microscope, scientists could finally see the tiny structures inside cells.

He was the first scientist to prove that cells can only form from pre-existing cells]]> 2019-02-08 13:33:05 UTC https://padlet.com/kianapagan319/7s5jtayamsug/wish/329177284 https://padlet.com/kianapagan319/7s5jtayamsug/wish/329177323  A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists.Van Leeuwenhoek is best known for his pioneering work in microscopy and for his contributions toward the establishment of microbiology as a scientific discipline., van Leeuwenhoek was the first to experiment with microbes, which he originally referred to as animalcules (from Latin animalculum = "tiny animal"). Through his experiments, he was the first to relatively determine their size. Most of the "animalcules" are now referred to as unicellular organisms, although he observed multicellular organisms in pond water. ]]> 2019-02-08 13:33:12 UTC https://padlet.com/kianapagan319/7s5jtayamsug/wish/329177323 https://padlet.com/kianapagan319/7s5jtayamsug/wish/329178636 He was a "natural philosopher"- an early scientist, his most notable discovery was in 1665 when he looked at a silver of cork through a microscope and discovered cells, but it was actually dead cell walls of plants which connects to the cell theory.
