Plant physiology. 414 VEGETABLE PHYSIOLOGY Threads of a delicate character may next be seen to extend from one centrosphere to the other, forming a body know as the nuclear spindle. The positions of the centrospheres are called the poles of the nucleus. When no centrospheres can be detected the threads of the spindle nevertheless converge to two similarly situated poles. Some of the spindle fibres stretch uninterruptedly from pole to pole, while others become in some way attached to, or entangled with, the chromosomes. The latter travel along these threads, with which their points are in contact, till they form a disc across the spindle (fig. 163, b). This stage is constant in all cases of karyokinesis, though some.
