In 1670, Antonie van Leeuwenhoek used a microscope to describe cells in a drop of pond water. He made his own fine quality lens for use in monocular microscopes, and he was the first person to observe bacteria and protozoa. Some of his lenses could magnify objects up to 250X.

Cell theory is the idea that cells are the basic unit of structure in every living thing. Development of this theory during the mid 17th century was made possible by advances in microscopy. The 1st man to witness a live cell under a microscope was Anton van Leeuwenhoek who in 1674 described the algae Spirogyra and named the moving organisms animalcules, meaning "little animals". Leeuwenhoek probably also saw bacteria. The observations of Leeuwenhoek & others led to the development of cell theory
Leeuwenhoek contributed to the cell theory unicellular bacteria in 1674. Leeuwenhoek improved the microscope so that he was able to magnify with much better resolution than Hooke, which encouraged his discovery.
the word leeuwenhoek means a veary mean dog that's a pig or a doverment
Robert Hooke, Anton van Leeuwenhoek, Mattias Shleiden, Theodor Schwann, and Rudolph Virchow
The cell theory
investigated the phenomenon of refraction deducing the wave theory of life.
I dont know how bout you ask him
Yes.
It was the development of the microscope that was significant in contributing to the development of the cell theory. All things that are alive are made up of cells.
Ludolph Christian Treviranus and Johann Jacob Paul Moldenhawer are credited for the formulation of Cell theory.
