The walls of cavities examined by Hooke were the walls of plant cells which form the tissue. The observation led to the introduction of the cells, a fact just possible after the invention of the microscope. In that work, Hooke established the word “cell”, now broadly employed in Biology, to designate such cavities seen beneath the microscope.
