Detailed explanation-1: -The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.

Detailed explanation-2: -Robert Hooke discovers dead cells using early microscope. Anton von Leeuwenhoek develops a more powerful microscope that allows him to see living cells like bacteria. Matthias Schleiden and Theodor Schwann conclude that all living organisms are made of cells, and that cells can be produced from other cells.

Detailed explanation-3: -While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells! Hooke’s discovery led to the understanding of cells as the smallest units of life-the foundation of cell theory.

Detailed explanation-4: -Robert Hooke observed cell by viewing thin slices of cork. He observed that the cork was made up of tiny hollow compartments separated from each other by wall or partition. He gave these compartment the name “cell”. Robert Hooke was actually observing dead plant’s cell wall and empty spaces.

Detailed explanation-5: -Robert Hooke, in 1665, observed thin slices of cork under a simple magnifying device. He observed box-like structures and named them the “cells"; as these reminded him of the cells in a monastery. Q. In which year did Anton van leeuwenhoek discover microscope?
