Robert Hooke observed cells in cork in 1665, naming the small compartments 'cells' from the Latin word meaning 'small room.' His observations were crucial in the development of cell theory, which states that all living organisms are composed of cells. The document also discusses the contributions of other scientists to cell biology and the differences between unicellular and multicellular organisms.
