[Extra information:

In 1665, the English scientist Robert Hook observed a cork slice through a primitive compound microscope and discovered a honeycomb structure. It was appearing like many tiny pores and he named them "cells". This word "cell" was taken from the Latin word Cella, which means 'a small room or compartment'. While coining the term "cell", Robert Hook did not know the real structure or function of the cell.

In the late 1830s, Botanist Matthias Schleiden and Zoologist Theodor Schwann proposed the unified cell theory, stating that all living things are composed of one or more cells and the cell is the basic unit of life.]
