The nuclear apparatus consists in the earliest stages offermentation of a nucleolus in close touch with a vacuole (Fig. 44, No. 4)which includes a granular chromatin network suggesting a similar struc-ture in the higher plants. The vacuole may disappear and then thechromatin granules are scattered through the protoplasm, or are gatheredaround the nucleolus, which is present in all of the cells, as a
