the Golgi apparatus, also called the Golgi body, was one of the first organelles to be discovered
in structure, the Golgi apparatus is made up of a series of compartments and is a collection of used, flattened membrane-enclosed disks known as cisternae, originating from clusters that bud off the endoplasmic reticulum
they sort proteins for transport to other organelles or outside of the cell
fun fact, it seems to be the only organelle that was named after a person: Camillo Golgi
