The nucleolus appears to form a part of t-he Linin network, but has usually also a strong affinity for nuclear stains.
The relation of the nucleolus to the chromosomes is clearly seen in the reconstruction of the daughter nuclei after division in the cells of the root-apex of Phaseolus (fig.
I, B) out of which is evolved the nucleolus and nuclear network (figs.
2, L), a nucleolus appears, a nuclear membrane is formed, and daughter nuclei are thus constituted which possess the same structure and staining reactions as the mother nucleus.
2, B), and this is preceded by a peculiar contraction of the thread around the nucleolus which has been termed synapsis (fig.
With nucleolus and plastid ~.
In other cases the two nuclei place themselves side by side, the nuclear membrane between them disappears, and the contents fuse togethernuclear thread with nuclear thread, and nucleolus with nucleolusso completely that the separate constituents of the nuclei are not visible.
7) the nuclei possess all the structures found in the higher plants, nuclear membrane chromatin network and nucleolus (fig.
Xxxviii.; Meyer, Untersuchungen fiber die Starke-Kdrner (J ena, 1895); Montgomery, Comparative Cytological Studies, with especial regard to the Morphology of the Nucleolus, Journ.
The nucleolus shows an unstainable point at the centre known as the endonucleolus or nucleoluolus (Auerbach).
Cell in process of karyokinetic division with retention of the nucleolus during the division.
Division of the nucleolus and formation of nuclear plate.
The nucleolus is elongated, and its longest measurement lies in the direction of the equatorial plane of the nucleus.
Division of the nucleolus by elongation, construction, and equilateral division of the nucleus.
Division of the nucleolus without any evidence of division of the nucleus.
In the earlier accepted notion of direct segmentation, usually known as the schema of Remak, division was described as commencing in the nucleolus, as thereafter spreading to the nucleus, and as ultimately implicating the cell-substance.
