Detailed explanation-1: -The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory .

Detailed explanation-2: -Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.

Detailed explanation-3: -Two types of electron microscopy-transmission and scanning-are widely used to study cells. In principle, transmission electron microscopy is similar to the observation of stained cells with the bright-field light microscope.

Detailed explanation-4: -The invention of the microscope allowed scientists to see cells, bacteria, and many other structures that are too small to be seen with the unaided eye. It gave them a direct view into the unseen world of the extremely tiny.

Detailed explanation-5: -In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke’s coining of the word “cell."
