We first observed that the head ofmature tentacle contained transfer cells which were pellet shape, thickness cytoplast, large nucleolus, developing endoplasm, small vacuole and thick cell wall.

The larger nucleolus was higher in electron-density, but the inside structure was not even, sometimes there was a very large nucleolar vacuole in it.

大核仁电子密度较高，质地不均匀，有时有一个体积很大的核仁泡位于其中。
