Robert Hooke in 1665, following the invention of the microscope, examined a thin slice of cork, noting thousands of ‘little boxes’ he called cells. Cork is dead – Hooke did not realize that the ‘little boxes’ had been produced by a transparent, jelly-like material that had died by the time the cork had fully developed. The importance of this jelly-like material was only appreciated many years later when biologists could see cell more clearly by staining them.
