Nucleus and Trophoplast A review of our knowledge concerning the anatomy of the nucleus can be regarded as superfluous in this con- nection. This knowledge is to be looked upon at present as an established achievement of science, the significance of which for the theory of heredity can hardly be doubted any longer. Flemming in the zoological, Strasburger and Schmitz in the bota...nical field have broken the way, and their observations have been verified and extended in the main by numerous other investigators. It does not seem to be quite fully decided whether the amitotic nuclei, which have originated through constriction and scission, are of significance in questions of heredity, or whether they occur in somatic cells only, and not on the germ-tracks. In Chara the nuclei in the apical cells divide, according to Johow's investigations, according to the usual scheme of indirect nuclear division ; the smaller cells of the grown plant, for example in the nodes, remain forever uni-nucleate, while the larger ones become multi- nucleate through constriction.
