Document Summary
He viewed slices of cork, cellula", noticing the little rooms". What he saw were the cell walls with no interior. Antoni van leeuwenhoek worked with glass and microscopes. He hugely improved the quality of lenses, almost 300x magnification became possible. Antoni van leeuwenhoek was the first to observe: He took bacteria from his own mouth; named the father of microbiology . Progress on cells stalled for about a century due to limited resolving power. There was an emphasis put on description rather than the explanation. The compound microscope was invented in the 1830s and further improved magnification and resolution of microscopes. Robert brown (botanist) noticed that plant cells contain a round structure; he called it a. What he actually observed was a nucleus. Matthias schleiden (botanist) found that all plant tissues are composed of cells. He noticed embryonic plants always arose from a single cell. Theordor schwann (zoologist) made similar observations to schleiden but in animal cells.
