Golgi body

The Golgi body is composed of stacks of a flattened series of membrane-bound sacs or cisternae, surrounded by a complex of tubes and vesicles. There  is a definite polarity across the  stack,  the  cis or forming face receiving vesicles  from  the  ER, the  contents of these vesicles then being processed by the Golgi, to be budded from the sides or the trans (maturing) face of the  organelle. The Golgi apparatus processes and packages materials for secretion into other subcellular organelles or from the cell membrane. Golgi bodies in fungi are less well developed than in algae, and tend to have fewer or single cisternae. They are sometimes termed dictyosomes.
