MICROANATOMY

Detailed explanation-1: -Antonie van Leeuwenhoek builds a simple microscope with one lens to examine blood, yeast and insects. He is the first to describe cells and bacteria. He invents new methods for making lenses that allow for magnifications of up to 270 times. Portrait of Antonie van Leeuwenhoek (1632–1723) by Jan Verkolje.

Detailed explanation-2: -Leeuwenhoek is universally acknowledged as the father of microbiology. He discovered both protists and bacteria [1]. More than being the first to see this unimagined world of ‘animalcules’, he was the first even to think of looking-certainly, the first with the power to see.

Detailed explanation-3: -Simple optical microscope A simple microscope is a microscope that uses only one lens for magnification, and is the original light microscope. Van Leeuwenhoek’s microscopes consisted of a single, small, convex lens mounted on a plate with a mechanism to hold the material to be examined (the sample or specimen).
