Golgi apparatus is an organelle that is found in most eukaryotic cells.
Functions of golgi apparatus are:
It involves the transport of lipids in cells.
It involves the formation of lysosomes.
It also takes part in glycosylation and phosphorylation of certain proteins

The golgi apparatus arises from the membrance of the smooth endoplasmic reticulum, which turns originates from the rough endoplasmic reticulum. The functions of golgi apparatus are -
- Golgi apparatus acts as a way - station or assembly area for storage, processing and packaging of various cellular secretions.
- Golgi apparatus packages materials synthesis in the cell
- Golgi apparatus contains vacoules which contain cellular secretions
- Golgi apparatus is involved in the synthesis of cell wall, plasma membrance and lysosomes
- Golgi apparatus is also known as Secretory

Golgi Complex:---- Also called a Golgi Apparatus, Golgi Body or dictyosome. A special set of membranous sacs, which collects, modifies and distributes the substances made by the ER (e.g. proteins). The substances fill the sacs, which gradually swell up at their outside edges until pieces "pinch off". These pieces, called vesicles then travel out of the cell via the cytoplasm and cell membrane

The Golgi apparatus is an important organelle of eukaryotic cells. Directing the carbohydrates and proteins required by the body to their correct destination is the primary job of Golgi body. In this process of directing molecules to appropriate destinations, they (molecules such as proteins and carbohydrates) are tagged with destination information and structural modifications.
functions of golgi apparatus-
- The main function of Golgi apparatus is to carry out the processing of proteins generated in endoplasmic reticulum. Along with the work of processing proteins, the Golgi apparatus also transports it to the different parts of cell.
- The Golgi enzymes present in membranous disks of cisternae carry out the modification of cargo proteins. Modification of various substances is carried out by enzymes in cisternae with the help of processes like phosphorylation and glycosylation.
- To carry out the glycosylation and phosphorylation processes, nucleotide sugars are imported by the Golgi apparatus from cytosol.
- Polysaccharides are attached with proteins in order to form carbohydrates.
- One of the tasks of Golgi apparatus is carrying out the breakdown of proteins and formation of small, active fragments.
- Sulfate groups are added to protein molecules in the Golgi apparatus.
- Incorporation of phosphate molecules onto molecules of proteins is also an important task carried out in the Golgi apparatus.
- Transportation of lipids around cells and creation of lysosomes are the important functions carried out by Golgi apparatus.
- Synthesis of proteoglycans is carried out by the Golgi body. The proteoglycans are found in extracellular matrix of animal cells.
- Carbohydrates are synthesized in the Golgi body. The process of carbohydrate synthesis involves production of polysaccharides and glycosaminoglycans (GAGs).
- The long, unbranched polysaccharides and GAGs are attached to proteins in order to form proteoglycans.
- The GAGs are polymerized by enzymes present in Golgi body with the help of xylose link; it leads to the formation of core proteins.
- Sulfation is an important task carried out by the Golgi body. The sulfation of substances passing through the lumen of Golgi body is carried out with the help of sulfotransferases.
- Golgi apparatus plays an important role in the prevention of destruction of cells (or apoptosis). The Bcl-2 genes present in the Golgi are used for this purpose.
