What is the function of the Golgi body in a cell?

The Golgi body, also known as the Golgi apparatus, plays a critical role in the process of modifying, sorting, and packaging proteins and carbohydrates that are synthesized in the cell. Once proteins and carbohydrates are produced in the endoplasmic reticulum, they are transported to the Golgi body. Here, they undergo further modifications, such as glycosylation, where sugars are added to proteins, and they are then packaged into vesicles for transport to their final destinations, either within the cell or for secretion outside the cell.

This function is essential for ensuring that proteins reach the correct location within the cell and that they are in the proper form needed for their specific roles. The Golgi body's ability to sort and package these molecules is vital for maintaining cellular organization and function. Other cellular structures have distinct roles; for example, chloroplasts are responsible for converting sunlight into energy, mitochondria control cellular respiration, and ribosomes are the sites of protein synthesis, but none of these tasks relate to the packaging function of the Golgi apparatus.
