What Unlike Hooke Leeuwenhoek observed cells that?

Unlike Hooke, who observed dead plant cells in cork and coined the term "cell," Antonie van Leeuwenhoek was the first to observe living cells. Using his handcrafted microscopes, Leeuwenhoek discovered microorganisms in pond water, blood, and dental scrapings, describing them as "animalcules." His observations provided a more dynamic view of cellular life, showcasing the diversity and complexity of living organisms at a microscopic level.
