EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.

Detailed explanation-3: -In 1676 Leeuwenhoek discovered bacteria in water. The bacteria were at the limit of observation of his microscope – he estimated that it would take more than 10, 000 of them to fill the volume of a small grain of sand.
