Document Summary
Introduction to the study of cell biology: cell biology started off with the invention of the microscope. The microscope is an instrument that provides a magnified image of a tiny object. Robert hooke (1665) is credited for the discovery of cells. He attempted to answer: why stoppers made of cork were so well suited to holding air in a bottle. He examined a cut piece of cork under a microscope and perceived what appeared to be pores which he labeled as cells . Anton van leeuwenhoek (1665-1675) spent spare time grinding lenses and constructing simple microscopes of remarkable quality. He was the first to examine a drop of pond water under a microscope. He was able to observe teeming microscopic animalcules that darted back and forth before his eyes. He was also the first to describe various forms of bacteria, which he obtained from water in which pepper had been soaked and from scraping of his teeth.
