The first person to use the word "cells" in a biological context was Robert Hooke in the 17th century. He used the term to describe the small compartments he observed in a slice of cork under a microscope, likening them to the cells in a monastery.

Robert Hooke used a compound light microscope to find cells. He found cells looking at cork and thought that they looked like cells.
Robert Hooke made significant contributions to botany through his work on plant anatomy, specifically his use of a microscope to observe plant cells. Hooke's detailed studies of plant structure, including his discovery of plant cells, laid the foundation for modern botany and our understanding of plant biology.
Robert Hooke first viewed cells with a microscope. He began calling them cells because they resembled the cells in which monks lived and worked.
Robert Hooke improved the design of the microscope and used it to make groundbreaking observations on the structure of various materials and biological specimens. His work, particularly in his book "Micrographia" published in 1665, helped popularize the use of microscopes in scientific research and laid the foundation for the field of microscopy.
In 1663, Hooke observed the structure of a thin slice of cork using a compound microscope he had built himself. Cork, the bark of an oak tree, is made up of cells that are no longer alive. To Hooke, the cork looked like it was made up of tiny rectangular rooms, which he called cells.
