Which two scientists contributed to cell theory by showing that both plants and animals are made of cells?

Explanation:
Cell theory hinges on the idea that all living things are made of cells. Schleiden studied plant tissues and concluded that plants are composed of cells, while Schwann studied animal tissues and reached the same conclusion for animals. Their complementary observations showed that the same basic unit, the cell, forms the building blocks of both plants and animals, laying the foundation of cell theory. Earlier observations by Hooke and Leeuwenhoek contributed to microscopic study, but it was Schleiden and Schwann who unified plants and animals under the idea that all organisms are made of cells.
