The Golgi Apparatus is the Processing, Packaging and Secreting Organelle of the Cell.
2. The Golgi Apparatus is a system of membranes. Made of Flattened SAC like Structures called CISTERNAE.
3. It works Closely with the ER, the Golgi Apparatus modifies proteins for export by the cell.
4. Golgi apparatus is also the site of producing vesicles called Lysosomes.
Cells contain several types of vesicles, which perform various roles.
2. Vesicles are small, spherically shaped sacs that are surrounded by a single membrane and that are classified by their contents.
3. Vesicles often migrate to and merge with the plasma membrane to release their contents outside of the cell
Lysosomes are small spherical organelles that enclose hydrolytic (digestive) enzymes within a single membrane.
Lysosomes are vesicles that bud (break off) from the Golgi apparatus and that contain digestive enzymes. 2. Lysosomes are the Site of Food Digestion in the Cell. They can break down large molecules such as proteins, nucleic acids, carbohydrates, and phospholipids.
3. In the liver, they break down glycogen to release glucose into the blood stream.
4. Some white blood cells use lysosomes to break down bacteria.
5. Within a cell, lysosomes digest worn-out organelles in a process called Autophagy.
6. Lysosomes are also responsible for breaking down cells when it is time for the cells to die - Apoptosis.
7. The digestion of damaged or extra cells by the enzymes of their own lysosomes is called Autolysis.
8. Lysosomes play a very important in maintaining an organism's health by destroying cells no longer functioning properly.
9. Lysosomes are common in the Cells of Animals, Fungi, and Protists, But they are Rare in Plant Cells.

Cells synthesise a large number of different macromolecules required for life. The Gogli apparatus is integral in modifying, sorting, and packaging these substances for cell secretion (exocytosis) or for use within the cell. It primarily modifies proteins delivered from the rough endoplasmic reticulum, but is also involved in the transport of lipids around the cell, and the creation of lysosome. In this respect it can be thought of as similar to a post office; it packages and labels "items" and then sends them to different parts of the cell.
Lysosomal vesicles
Vesicle contains proteins destined for the lysosome, an organelle of degredation containing many acid hydrolases, or to lysosome-like storage organelles. These proteins include both digestive enzymes and membrane proteins. The vesicle first fuses with the late endosome, and the contents are then transferred to the lysosome via unknown mechanisms.
***Digestive proteases destined for the lysosome

The vesicle / sacs from golgi bodies bud off from them, forming lysosomes.

lysosome is a type of vesicle that the golgi body produces. it contains hydrolytic enzymes(packed inside the vesicle by the golgi) and can digest organelles and material engulfed by cells

Golgi's complex is basically just a stack of membrane, membrane breaks off from Golgi's to form more membrane, in this case lysosomes.
