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. Specifically, he observed that “the lower plants all consist of one cell, while the higher ones are composed of (many) individual cells.”.
