Under these microscopes, Leeuwenhoek found motile objects. WebAnton Van Leeuwenhoek and The Cell Theory He began to analyze human tissue for cells. No one else was able to see things as small as Leeuwenhoek. He was most well known for his discovery of protozoa in 1674. Robert Brown & Cell Theory | Background, Discovery & Contributions. Leeuwenhoek's work was very important to debunking the theory of spontaneous generation. He was skilled in crafting these lenses in a way that he could see single-cell organisms which was something no one else was able to do before. Van Leeuwenhoek also discovered the existence of sperm in mammals in 1677, something he considered his most significant discovery. There are three tenets of the cell theory: Leeuwenhoek is a scientist who created lenses to refine the microscope. While he clearly distinguished between observation and scientific theory, his letters sometimes included digressive comments and personal opinions. Later advances in lenses, microscope construction, and staining techniques enabled other scientists to see some components inside cells. The original cell theory states that the cell is the basic structural and functional unit of living organisms and all cells come from other cells.

Despite the limitations of his now-ancient lenses, van Leeuwenhoek observed the movements of protista (a type of single-celled organism) and sperm, which he collectively termed animalcules. However, Van Leeuwenhoek was the first person to develop a lens of such superior quality. Anton van Leeuwenhoek was inspired by the By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. In a 1665 publication called Micrographia, experimental scientist Robert Hooke coined the term cell for the box-like structures he observed when viewing cork tissue through a lens.

His studies of insects, mollusks, and fish showed that these animals did not begin their life cycle with spontaneous generation, from nonliving matter. Through this study, he was able to conclude how fertilization occurred by sperm uniting with eggs. We are also more knowledgeable now of the world of microbiology and how these tiny organisms work to sustain the circle of life.
