anton van leeuwenhoek contribution to cell theory
He was the first to observe live cells in a sample of pond water. Thus, Schleiden and Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. Contributed to cell theory by believing that there were seeds or eggs too small to see by the eye being planted into food, and other things. 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. 
He is best known for his pioneering work in microscopy, particularly in the use of the microscope to observe and describe the structure and function of living cells. After this lesson is completed, students should be able to recall who Anton Van Leeuwenhoek was and describe his major scientific discoveries. His researches on lower animals refuted the doctrine of spontaneous generation, and his observations helped lay the foundations for the sciences of bacteriology and protozoology. Anton Van Leeuwenhoek contributed to cell theory through his observations where he first described living cells as red blood cells. During a long life he used his lenses to make pioneer studies on an extraordinary variety of things, both living and non-living, and reported his findings, Matthias Schleiden found that all plants are composed of cells, and communicated the finding to Schwann, who had found similar structures in the cells. His letter announcing this discovery caused widespread doubt at the Royal Society but Robert Hooke later repeated the experiment and was able to confirm his discoveries. Due to his observations, we understand today that cells come from other cells. In the 1670s, van Leeuwenhoek discovered bacteria and protozoa. His most famous work was discovering spermatozoa as well as bacteria.
Leeuwenhoek remarried in 1671; his second wife died in 1694. Because of this association, Hooke called them cells, the name they still bear. Theodor Schwann The classical cell theory was proposed by Theodor Schwann in 1839. A component of the cell theory is that the cell is the basic unit of life. These tiny single-cell organisms are known today as microorganisms and Leeuwenhoek went on to be known as the Father of Microbiology. in 1674 he algae and animalcules.

Van Leeuwenhoek also discovered the existence of sperm in mammals in 1677, something he considered his most significant discovery. His findings were written in Dutch. Under these microscopes, Leeuwenhoek found motile 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. He maintained the same to be true of the freshwater mussel, whose embryos he examined so carefully that he was able to observe how they were consumed by animalcules, many of which, according to his description, must have included ciliates in conjugation, flagellates, and the Vorticella. Under these microscopes, Leeuwenhoek found motile objects. Francesco Redi Experiments & Cell Theory | Who was Francesco Redi? Webthe theory of relativity musical character breakdown.

Cells arise from other cells through cellular division. He concluded that all cells come from preexisting cells. Leeuwenhoek made microscopes consisting of a single high-quality lens of very short focal length; at the time, such simple microscopes were preferable to the compound microscope, which increased the problem of chromatic aberration.

By the time of her death, in 1666, the couple had five children, only one of whom survived childhood. His aphorism'omnis cellula e cellula' meaning every cell from a pre-existing cell became the foundations of division, even if the process was not fully understood then. In 1670, Leeuwenhoek significantly improved the quality of microscope lenses to the point that he could see the single-celled organisms that lived in a drop of pond water.
