GlenodiniumfoliaceumStein（甲藻门）具有一个中核，核内含有大量典型的甲藻染色体和一个或多个核仁，核仁结构与高等生物的核仁相似。此外，这种生物体还具有另一种核样细胞器，在此称为真核细胞核。这是一种多形体，其形状从卵圆形到分支丝状形式变化。与中核一样，它被有孔的被膜包围。细胞器含有颗粒状物质，通常含有几个核仁，这些核仁又具有典型的核仁形态。在其他甲藻中没有发现两个不同类型的核，本文讨论了这两个核的功能和意义。
Glenodinium foliaceumStein (Pyrrophyta) has a single mesocaryotic nucleus which contains numerous typically dinoflagellate chromosomes and one or more nucleoli with a structure similar to that of nucleoli in higher organisms. In addition this organism possesses another nucleus-like organelle which is here termed the eucaryotic nucleus. This is a polymorphic body which varies in shape from ovoid to a branched filamentous form. As with the mesocaryotic nucleus it is surrounded by a perforated envelope. The organelle contains granular material and usually several nucleoli which again appear to have the typical form of nucleoli. No other dinoflagellate is known in which two nuclei of differing types are found. The function and significance of the presence of the two nuclei is discussed.
