Detailed explanation-1: -Robert Hooke discovered cell in the year 1665. He observed cork cell in the bark of Spanish oak tree under a simple microscope and was able to see the empty structures surrounded by walls and named it a cell. He elucidated his observation in a book called “Micrographia".

Detailed explanation-2: -Cells usually have a nucleus and cannot be hollow. As the cells in the cork were dead they lacked cytoplasm and nucleus. Hence, Robert Hooke observed dead enucleated cells under the microscope.

Detailed explanation-3: -Hooke had discovered plant cells–more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term “cells": the boxlike cells of cork reminded him of the cells of a monastery. Hooke also reported seeing similar structures in wood and in other plants.

Detailed explanation-4: -Background: Important Figures in Cell History: Robert Hooke was an English scientist who looked at a thin slice of cork (oak cork) through a compound microscope. He observed tiny, hollow, room-like structures that he called ‘cells’ because they reminded him of the rooms that the monks lived in.

Detailed explanation-5: -The cork was full of small empty compartments separated by thin walls. He called the compartments “pores, or cells.” He estimated that every cubic inch of cork had about twelve hundred million of these cells. Robert Hooke had discovered the small-scale structure of cork.
