The cell was first discovered and was made known by an English man Robert Hooke (1635-1702) in the year 1665 while looking down his microscope onto a cork twig. He saw a pore like structure made up of many small rooms.
Hence, the word cell, which comes from the Latin cellular, meaning a small room.
This marks the first visual of biological organisms and Robert Hooke went on to publish Micrographic, a book describing his microscopic and telescopic observations.
Soon after that a Dutch tradesman Antonie van Leeuwenhoek (1632-1723) inspired by Hooke's book, continued the research of cells and earned himself as the first microbiologist.
In 1831 scientists in England discovered that there were 2 types of cells, the Prokaryotic and Eukaryotic cell but their importance was still not known.
In between 1830-1839 a German agriculturist M.J.Scheiden (1804-1881) and a psychiatrist T.Schwan (1810-1882) combined their efforts in cell studies which lead them to understand the importance of the cell function. It is then known that cells are what we are made of, and is the foundation of life.
Therefore, where the discussions of life are concerned, scientists and medical professionals say that the origin of life is from the cell itself.
