In 1665, Robert Hooke made the revolutionary discovery of the cell. Through the use of a microscope, Hooke was able to see what he believed was a plant cell, though, in actuality, Hooke was looking at dead cell walls that belonged to a piece of cork. At the time, Hooke was unaware of the fact but it did not stop him from naming his observation "cell". He called it this because he noticed the cork had tiny, room-like indentations which reminded him of cellulas or small rooms monks lived in.
