Rudolf Virchow proved that cells come from preexisting cells.
Theodor Schwann discovered that animals are composed of cells.
Matthias Schleiden discovered that plants are made of cells.
The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van Leeuwenhoek. Despite the limitations of his simple microscope, van Leeuwenhoek observed some cells he termed "animalcules." Robert Hooke then coined the term "cell" for the box-like structures he observed when viewing cork tissue through a lens. Later advances in lenses, microscope construction, and staining techniques enabled other scientists to see some components inside cells. Just as the microscope has been a work in progress with advances that have led to our current technology, so the cell theory changed as new discoveries changed the understanding of cells.
