Description: "Purkinje (1787-1869) is one of the great geniuses in the field of biological discovery." (Nordenskiöld). As a master microscopist, one of Purkinje's earliest studies with a simple microscope (he acquired a compound Plössl achromatic in 1832) was that of anthers of flowering plants. Here the role of cells in the differentiation of plant tissues and an anticipation of Robert Brown's discovery of pollen movement and the cell's nucleus are given. "Purkinje studied plant structures, mainly the elastic fibrous cells of the anthers and the form of the pollen and spores in relation to the mechanism of their dispersion. In his extensive comparative study, combining anatomy with physiology, he distinguished structural types and drew attention to mechanical factors and the role of cells in the differentiation of plant tissues." (D.S.B.).
