Golgi Apparatus (Golgi Complex or Golgi Bodies)
Golgi Apparatus (Golgi Complex or Golgi Bodies) is a cellular organelle found in Eukaryotic cells.
Golgi Apparatus plays an important role in processing and sorting of proteins and lipids which are synthesized in the Endoplasmic Reticulum and also preparing them for distribution to their final destinations.
Golgi Apparatus acts as a central post office, where the proteins or lipids are packaged, labeled and sent to their final destinations which includes the plasma membrane, lysosomes, secretory vesicles etc.

Diagram Golgi Apparatus
Description of Golgi Apparatus (Golgi Complex or Golgi Bodies) labels is as follows-
Cis face
Cis Face of the Golgi refers to the end closest to the Endoplasmic Reticulum (ER), where newly synthesized proteins and lipids vesicles enter.

Incoming Transport Vesicle
Incoming Transport Vesicles are formed in the Endoplasmic Reticulum (ER) .It carries newly synthesized proteins to the Golgi apparatus for further modification and sorting. It fuses with the Golgi cis face and releases their contents, forming a growing stack of cisternae.
Cisternae
The Golgi apparatus consists of a series of flat stacked membranes called Cisternae. Proteins are sorted and modified as they move through the cisternae from the cis face to the trans face.
Lumen
Lumen is the interior space of the Golgi apparatus. It is surrounded by the cisternae and filled with a fluid that helps in the sorting and modification of the proteins.
Secretory Vesicle
Secretory Vesicles form in the Golgi apparatus and carry modified proteins to their final destination like the plasma membrane for exocytosis or other intracellular compartments.
Trans face
Trans face is the side of the Golgi apparatus that faces away from the Endoplasmic Reticulum where the modified proteins and lipids are packaged into secretory vesicles.
Newly forming Vesicle
Newly forming Vesicle is the vesicle which is in the process of forming in the Golgi apparatus and has not yet reached its final destination.
