Dictyosomes are stacks of flat, membrane-bound cavities (cisternae) that together comprise the Golgi apparatus. Within the dictyosomes, proteins are stored, modified, sorted, and packed into vesicles (which are then closed off as Golgi vesicles) for further transport. Whereas dictyosomes in animal cells are stacked tightly together, the dictyosomes in plant cells are dispersed in the cytoplasm, making them difficult to identify as the Golgi apparatus.


A stack of multiple cisternae (flat membrane-bound structures).

Interior forms secretions. Taken together, all of the dictyosomes of a cell make up its Golgi apparatus.

Closes off Golgi vesicles: bubbles that enclose substances to be transported out of the cell.
