Antony Van Leeuwenhoek first discovered bacteria in pond, which is filled with dirty rain water, with a microscope made by him.

Robert Hooke discovered cell in the year 1665. He observed cork cell in the bark of Spanish oak tree under a simple microscope and was able to see the empty structures surrounded by walls and named it a cell. He elucidated his observation in a book called "Micrographia".

The cell was discovered by Robert Hooke in 1665 when he saw an empty box like compartments in a very thin slice of cork under his microscope. He wrote a book 'Micrographia' and coined the term cellulae which was later changed into the cell.

Antony Van Leeuwenhoek was a tradesman of Holland. He made microscope and discovered bacteria.

Robert Brown discovered an opaque area in many plant cells when observed under the microscope. He called it the nucleus.

An electron microscope uses a beam of accelerated electrons as a source of illumination, allowing for much higher magnification and resolution than light-based microscopes.

Zacharias Janssen was the first scientist who is responsible for the invention of the compound microscope. The scientist worked and manufactured the different type of lenses. He made a cylindrical tube-like structure and arranged many different lenses in different orientations within the tube. This led to the formation of the compound microscope which was also known as the telescope. 

Leeuwenhoek, Pasteur, and Spallanzani all made foundational contributions to microbiology, ranging from the discovery of microorganisms to the debunking of spontaneous generation.
