So we see that the Golgi apparatus is the organelle where we basically organize, modify, and ship all the proteins throughout the cell, throughout the membrane and outside the cell. It's the place where we form lymphosomes. It's also place where we form polysaccharides. We modify our proteins in many different ways. Now, the rough endoplasmic reticulum primarily functions to create our proteins that end up being placed either into the cell membrane or leave the cell entirely. And our smooth er has several important functions.
