( x 800.) separated into two groups, delicate connecting fibrils are seen tobe stretched between them ; these, according to Strasburger(VI. 73), are derived from the central portions of the spindle fibrils(Fig. 94 /). After a time, in the middle of the connecting fibrils,small swellings, which look like glistening granules, are formed(Fig. 94 g). They are most regularly arranged, so that they areseen in optical section to lie close to one another in a row. Thuscollectively they form a disc, composed of granules, and situated inthe division plane between the two daughter-nuclei ; this disc hasbeen called the cell plate by Strasburger.
