The phospholipid bilayer can reach out with its membrane, and engulf proteins and lipid incoming to the cell. This is known either as Pinocytosis or Phagocytosis- both are forms of endocytosis of the cell.
Pinocytosis is the ingestion of dissolved materials by endocytosis where the cell membrane invaginates and pinches off small droplets of fluid in a pinocytotic vescile.
In Phagocytosis, the cell membrane invaginates and pinches off, putting the proteins or lipids in a phagocyotic vacuole (endosome) and it fuses with lysosomes that digests the contents.

Golgi Bodies
Golgi bodies
Golgi bodies make the vesicles
The Golgi apparatus takes simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them into vesicles, and either stores them for later use or sends them out of the cell. It also builds lysosomes, creates complex sugars and sends them off in secretory vesicles.
The Golgi bodies. Vesicles = packes, Golgi bodies = UPS.
Bodies which pinch off vesicles at end
exocytosis....think exo like exit
Golgi bodies make the vesicles
Vacuole or vesicles are used to transport proteins and other molecules out of cells. These secretory vesicles are actually a part of Golgi bodies. After synthesis, protein undergoes modifications in ER and Golgi, where it packaged in those vesicles.

"The Golgi body and its vesicles function in the sorting, modifying, and packaging of macro-molecules that are secreted by the cell or used within the cell for various functions."
Actualy glycogen is not a protein but it is a polymer of glucose molecules stored in animal bodies and used as energy source when needed.
