______ discovered the cell in 1665.

Robert Hooke discovered cells in 1665 when he examined cork slices under a primitive microscope and observed tiny box-like structures. He coined the term 'cell' because they reminded him of monks' living quarters in a monastery. Leeuwenhoek was a great microscopist but his work came later and focused on microorganisms like bacteria and protozoa.
