Computer-generated three-dimensional reconstructions of higher plant dictyosomes from electron micrographs are presented from different viewing angles in the form of shaded perspective displays. The image processing has revealed complicated structures indicating a central cisternal stack surrounded by a cloud of vesicles and vesicular and tubular protrusions. The entire dictyosome is suggested as being an approximately spherical body that is marginally penetrated by plates and tubules of the endoplasmic reticulum.

Key words: Golgi apparatus, three-dimensional reconstruction, computer image display
