What is the cell theory of Leeuwenhoek?
Anton Van Leeuwenhoek and The Cell Theory Leeuwenhoek wanted to go smaller than cork cells. He began to analyze human tissue for cells. He was most well known for his discovery of protozoa in 1674. In 1678, Leeuwenhoek discovered bacteria and called them "animalcules" or "little animals".
Are animalcules fungi?

What did Leeuwenhoek discover?
Leeuwenhoek is universally acknowledged as the father of microbiology. He discovered both protists and bacteria (1). More than being the first to see this unimagined world of 'animalcules', he was the first even to think of looking—certainly, the first with the power to see.
What was Rudolf Virchow cell theory?
Virchow's theory stated that just as animals are unable to arise without previously existing animals, cells are unable to arise without previously existing cells. The idea that new cells arose from pre-existing cells in both diseased and healthy tissue was not original.

Virchow's greatest accomplishment was his observation that a whole organism does not get sick—only certain cells or groups of cells. In 1855, at the age of 34, he published his now famous aphorism “omnis cellula e cellula” (“every cell stems from another cell”).
