Matthias Jacob Schleiden studied microscopic plant structures. In his studies, he observed that the different parts of the plant organism are composed of cells or derivatives of cells.
Plant cells were first discovered in the 17th century by scientist Robert Hooke, a genius whose contributions to science were wide-ranging and diverse. In 1665, he published a book called “Micrographia” that contained drawings and descriptions of objects he had observed through the microscope.
This book contained history’s first use of the word “cell” to describe the basic unit of life. While studying cork slices through the microscope, Hooke noticed they were composed of honeycomb-like structures that reminded him vaguely of the cells in a monastery.
Today it seems obvious that all living things are made of cells; but this theory, one of the foundations of modern biology, was once a novel idea. The existence of cells was completely unknown until the 17th century.
