May 13, 2020 · The ideas of all three scientists — Schwann, Schleiden, and Virchow — led to cell theory, which is one of the fundamental theories unifying all of biology. Cell theory states that: All organisms are made of one or more cells. All the life functions of organisms occur within cells. All cells come from already existing cells.
Oct 19, 2023 · German scientists Theodore Schwann and Mattias Schleiden studied cells. Schwann studied animal cells and Schleiden studied plant cells. These scientists found key differences between the two cell types. They had the idea that cells were the simplest units of both plants and animals.

Jul 30, 2022 · A cell is the smallest unit of life. Most cells are so tiny that they cannot be seen with the naked eye. Therefore, scientists use microscopes to study cells. The first microscopes were used in the 1600s by Antony van Leeuwenhoek, a Dutch shopkeeper who had great skill in crafting lenses.
