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: -Then, in the 1950s, a new type of the microscope was invented. Called the electron microscope, it used a beam of electrons instead of light to observe extremely small objects. With an electron microscope, scientists could finally see the tiny structures inside cells.

Detailed explanation-3: -Because most cells are too small to be seen by the naked eye, the study of cells has depended heavily on the use of microscopes.

Detailed explanation-4: -It made it possible to actually see cells. Explanation: With the development and improvement of the light microscope, the theory created by Sir Robert Hooke that organisms would be made of cells was confirmed as scientist were able to actually see cells in tissues placed under the microscope.

Detailed explanation-5: -The development of the microscope allowed scientists to make new insights into the body and disease.
