Robert Hooke discovered _______

Correct option is C

The correct answer is (c) Cell.
· Robert Hooke was an English scientist who, in 1665, used a microscope to observe the structure of a thin slice of cork.
· He noticed that the cork was made up of tiny, hollow compartments, which he referred to as "cells." This term came from the Latin word "cella," meaning a small room.
· Hooke's observation marked the first recorded identification of cells, laying the foundation for cell theory.
· His work was published in his book "Micrographia," which detailed his findings and the significance of microscopic observations.
