Cell are the basic 'structural unit' of all living beings. They remained undiscovered for a long time because the majority of the cells are too small to be seen by the unaided eye.

It was only after the advent of optical instruments, in the seventeenth century, that the cell was discovered and its basic features were studied.

Robert Hooke was the first scientist who, in 1665, observed thin slices of cork (obtained from a bark of a tree) through his self-designed microscope. He observed that they had honey-comb like structures consisting of little compartments (in Latin, 'cell' means 'a little room'). It was later explained that these 'compartments' were actually 'dead cells', bound by a 'cell wall'.
