Cells carry genetic material passed to daughter cells during cellular division, All cells are essentially the same in chemical composition, Energy flow (metabolism and biochemistry) occurs within cells. In order to observe phenomena as small as bacteria, Leeuwenhoek must have employed some form of oblique illumination, or other technique, for enhancing the effectiveness of the lens, but this method he would not reveal. He only had curiosity and skill with lenses. He also made over 500 microscopes to view specific objects. He taught himself new methods for grinding and polishing tiny lenses of great curvature which gave magnifications up to 270x diameters, the finest known at that time.
