Detailed explanation-1: -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-2: -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-3: -Robert Hooke in 1665 observed thin slices of cork under a simple magnifying device. He observed box-like structures and coined the term “cells” for them as these reminded him of the cells in a monastery.
Detailed explanation-4: -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.
Detailed explanation-5: -Robert Hooke observed a thin slice of cork under a crude microscope. He was an architect who was the first person to visualise a microorganism and found several architectural surveys. Robert Hooke discovered parenchyma cells in the 17th century.
