Robert Hooke. Robert Hooke FRS (/ hʊk /; 18 July 1635 – 3 March 1703) [ 4 ][ a ] was an English polymath who was active as a physicist ("natural philosopher"), astronomer, geologist, meteorologist and architect. [ 5 ] He is credited as one of the first scientists to investigate living things at microscopic scale in 1665, [ 6 ] using a ...
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s. In this theory the internal contents of cells were called protoplasm and described as a jelly-like substance, sometimes called living jelly.
Great Britain. Micrographia: or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses. With Observations and Inquiries Thereupon is a historically significant book by Robert Hooke about his observations through various lenses. It was the first book to include illustrations of insects and plants as seen through microscopes.
1665: Robert Hooke publishes Micrographia, a collection of biological drawings. He coins the word cell for the structures he discovers in cork bark. 1674: Antonie van Leeuwenhoek improves on a simple microscope for viewing biological specimens (see Van Leeuwenhoek's microscopes).
Since the invention of the microscope in the seventeenth century it has been known that plant and animal tissue is composed of cells : the cell was discovered by Robert Hooke. The plant cell wall was easily visible even with these early microscopes but no similar barrier was visible on animal cells, though it stood to reason that one must exist.
Cells were first seen in 17th-century Europe with the invention of the compound microscope. In 1665, Robert Hooke referred to the building blocks of all living organisms as "cells" (published in Micrographia) after looking at a piece of cork and observing a cell-like structure; [4] [5] however, the cells were dead. They gave no indication to ...
1665: Robert Hooke discovered cells in cork, then in living plant tissue using an early compound microscope. He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40]
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) ' life ' and -λογία (-logía) 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells). [1][2] Microbiology encompasses numerous sub ...
