Through which microscope were cells first observed?
poizon [28]

Compound microscope

<h3>Further explanation</h3>

In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.

Development of microscopy:

  • 1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
  • 1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
  • 1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
  • 1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.

Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.
