Explain the Discovery of Cell
Let us study here about the scientists who played a pioneer role in discovering the basic component of any living organism -the cell. Robert Hooke (1665) is credited with the discovery of cell. Hooke observed a honeycomb-like pattern in a very thin slice of cork as shown in the Figure. As you can see, this honeycomb-like structure consists of a thick wall, enclosing box-like compartments for which he coined the term cellulae for the first time and this term is synonymous to what we call as cells. He regarded cellulae as passages for conducting fluids.
Antony Van Leeuwenhoek, on the other hand, was the first to observe free cells. You may already be aware that these are single organisms.
