context: The first person to see the cells was the English scientist Robert Hook (known for discovering Hooke's law). In 1665, trying to understand why the cork tree floats well, Hook began to examine thin sections of the cork with the help of an improved microscope. He found that the cork was divided into many tiny cells that reminded him of honeycombs in the hives of honey bees, and he called these cells cells (in English, cell means “cell, cell”).
