GOLGI APPARATUS Meaning and
Definition
-
The Golgi apparatus, also known as the Golgi complex or Golgi body, is an essential organelle found in eukaryotic cells. It is named after Camillo Golgi, an Italian biologist who first observed and described its presence in the late 19th century.
The Golgi apparatus plays a pivotal role in the processing, sorting, and packaging of proteins and lipids within the cell. It consists of a series of flattened membrane-bound sacs called cisternae, which are stacked on top of one another. These cisternae are interconnected by small vesicles, forming a complex network within the cytoplasm of the cell.
One of the main functions of the Golgi apparatus is to modify proteins and lipids received from the endoplasmic reticulum. This includes the addition of carbohydrate chains (glycosylation), the cleavage of unnecessary parts, and the formation of disulfide bonds. Additionally, the Golgi apparatus plays a critical role in sorting and directing molecules to their final destinations, either within the cell or for secretion outside the cell.
Furthermore, the Golgi apparatus is involved in the formation and packaging of secretory vesicles, which transport molecules to different parts of the cell or external destinations such as the cell membrane for exocytosis. It also participates in the recycling of cellular components and the synthesis of certain complex molecules.
In summary, the Golgi apparatus is a key organelle responsible for post-translational modifications, sorting, and packaging of proteins and lipids. Its complex structure and intricate processes ensure proper cellular function and facilitate intercellular communication and transport.

Etymology of GOLGI APPARATUS
The word "Golgi Apparatus" is named after its discoverer, Camillo Golgi, an Italian physician and biologist. In 1898, Golgi observed a network of interconnected sacs in the cytoplasm of cells, and he proposed that it played a role in cellular structure and function. This cellular structure was later named the "Golgi Apparatus" in his honor.
