In 1665, an English scientists named Robert Hooke made a simple microscope and looked at a piece of cork, the dead cells of oak bark. Hooke observed small, box shaped structures such as those shown below. He called them cellulae (Latin for small rooms) because the box like cells of cork reminded him of the cells in which monks live at the monastery.
