Fig. 5a: Golgi stack at ER transition zone and Golgi cisternae

The Golgi complex of Paramecium multimicronucleatum consists of many elements called dictyosomes scattered in the cell. The dictyosome in this trifluoperizine-treated cell is easily recognized and has the usual components of a Golgi stack, a transition zone (1) of the ER, a zone of COP-II coated transition vesicles (2) budding from the ER and two layers (3 and 4) of highly fenestrated cisternae presumably composed of the fused transition vesicles.
