Golgi apparatus

This article describes an organelle, a cell component with its own distinctive structure and function. In eukaryotic cells, this is bounded by its own membrane, which is a lipid bilayer made of phospholipid.
Unless otherwise specified, information about this organelle is about its in situ occurrence in vivo, i.e., its occurrence in its usual location in living cells.

Definition

The Golgi apparatus (also called the Golgi body or Golgi apparatus) is an organelle found in most eukaryotic cells whose function is to package proteins (after their synthesis by the ribosomes) in a form that can be secreted via vesicles.
