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: -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-3: -Mature cork cells are plant cells that form the protective water-resistant tissue in the outer covering of stems or trunks. Cork cells are genetically programmed not to divide, but instead to remain as they are, and are considered dead cells.
