6/14 The emission of the gemmules takes place, or may take place in all states of the cell. The quantity of gemmules emitted from every cell is very great. The minuteness of the gemmules is extreme. The gemmules possess two sorts of affinity, one of which might be called _propagative_, and the other _germinative_ affinity. By means of the propagative affinity all the gemmules emitted by all the cells of the individual flow together and become condensed in the cells which compose the sexual organs, whether male or female (embryonal vesicle, cells of the embryo, pollen grains, fovilla, antherozoids, spermatozoids), and likewise flow together and become condensed in the cells which constitute the organs of a sexual or agamic reproduction (buds, spores, bulbilli, portions of the body separated by scission, &c.). |
