Golgi Body

The Golgi Body is named after the Italian cytologist, Camillo Golgi. Most eukaryotic cells contain one or more Golgi bodies, the organelle being particularly abundant in cells that secrete glycoproteins and mucopolysaccharides. The Golgi body is composed of a stack of membrane-bound compartments called cisternae that receive proteins from the rough endoplasmic reticulum (rer). Once received, the Golgi body modifies the proteins and directs them to the correct destination in the cell. Unlike the cisternae of the rer, those of the Golgi body are not directly connected. The cisternae are also often curved so that each has a convex and concave side. Closely associated with the cisternae are membrane-bound vesicles (labelled 'v' on the image below). The part of the Golgi body closest to the rer that receives the proteins, is known as the cis face (top of image) and that side of the Golgi that dispatches the modified proteins the trans face (bottom of image).

In plant cells the Golgi body is usually referred to as the dictyosome.
