A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins, receiving them from the rough endoplasmic reticulum and directing them to secretory vesicles, lysosomes, or the cell membrane. The movement of proteins takes place by transfer vesicles that bud off from the rough endoplasmic reticulum or Golgi apparatus and fuse with the Golgi, lysosomes or cell membrane. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990)
A cytoplasmic organelle that consists of a stack of smooth membranous saccules and associated vesicles and that is active in the modification and transport of proteins -- called also Golgi complex.
