摘要:
Some ultrastructural features of cells of the marine haptophycean alga,Ochrosphaera neapolitanaSchussnig in the palmelloid stage were examined. Chloroplasts which are contained in a compartment isolated from the cytoplasm by ER profiles and nuclear envelope, display trilamellated thylakoids running along the major axis. The stalked pyrenoid with inner bilamellated thylakoids, protrudes in a large membrane-bounded vacuole. Other structures, as the haptonematic and flagellar bases, autophagic vacuoles and mitochondria, are typical of the chrysophycean and haptophycean genera so far investigated.
