The Golgi apparatus is abundant in secretory cells, such as cells of the pancreas. BACK TO CELL IMAGE Golgi Vesicle: A membrane-bound body that forms by budding from the Golgi apparatus. It contains proteins (glycoproteins), such as digestive enzymes, and migrates to the cell (plasma) membrane.Golgi vesicles fuse with the cell membrane and discharge their contents into the exterior of the cell through a process called exocytosis.inocytotic Vesicle: A membrane-bound vacuole formed by a specific type of endocytosis called pinocytosis. The plasma membrane invaginates (pinches inwardly) to form a vesicle that detaches and moves into the cytoplasm.
