Cell theory was created upon the discovery of cells, which was done through a primitive microscope by Robert Hooke in the 17th century. Hooke made the discovery while observing plant tissues. As microscopes became more powerful over the years, it became possible not only to identify which type of cells are being observed, but what organelles and other structures are contained in each cell.
