He used a microscope and examined a cork and saw many small many small rooms. Hooke decided to call it "Cells" because it looked like an empty room. There are many roles in a cells, and they all have specific roles. Without one role of the cell, the cell would not function properly. The cell creates tissues, and tissues create body organs.
