Robert Hooke

Cell structure and function of Class 8

The cell was discovered by Robert Hooke in 1665. He examined (under a coarse, compound microscope) very thin slices of cork and saw a multitude of tiny pores that he remarked looked like the walled compartments a monk would live in. Because of this association, Hooke called them cells, the name they still bear. However, Hooke did not know their real structure or function. Hooke's description of these cells (which were actually non-living cell walls) was published in Micrographia. His cell observations gave no indication of the nucleus and other organelles found in most living cells.

Robert Hooke wrote Micrographia, the first book describing observations made through a microscope. The drawing to the top left was created by Hooke. Hooke was the first person to use the word "cell" to identify microscopic structures when he was describing cork. Hooke also wrote Hooke's Law - a law of elasticity for solid bodies.
