Detailed explanation-1: -About 350 years ago, lens grinder and scientist Anton van Leeuwenhoek peered into his microscope at a sample of pond water and discovered a whole world of creatures too small to see with the unaided eye. He thought these creatures were animals the size of molecules, so he termed them “animalcules”.
