We don’t really think of cells. They’re so small that we don’t pay attention to them thinking that they don’t matter much. Well, the truth is they matter as much as any other thing. These tiny cells are not called the building blocks of life for nothing. And these cells are not just circular or squarish structures with that have nothing in them. They are far more complex than that.
These cells are pretty much like a small model of our own bodies. There are various parts that work within the cell that enable it to function in the best way possible. One of these structures is the Golgi apparatus. But what is it? What is the Golgi apparatus and what does the Golgi apparatus do?
The Golgi apparatus is an organelle present in most eukaryotic cells. It was discovered by the Italian doctor, Camillo Golgi, and thus, the name. The Golgi apparatus is also known as the Golgi complex or Golgi body.
As I have mentioned earlier, the cell is like a minute model of our bodies. The Golgi apparatus is called an organelle because it functions like a small organ. It acts as a transport system inside your cell. It works very much like a delivery or shipping system. The Golgi apparatus gathers simple molecules and combines them to make more complex molecules. These complex molecules are then packed into vesicles by the Golgi complex and then are either stored for later use or sent out of the cell.
The Golgi apparatus in plant cells are also responsible for creating complex sugars and sending them off through secretory vesicles. The vesicles are similar with the endoplasmic reticulum vesicles. They are pinched off the membranes and are then allowed to float through the cell.
Another function of the Golgi apparatus is the building of lysosomes. Lysosomes are cell digestion machines. They break down the food with the enzymes present in them. The lysosomes can also break down other organelles when there is no food present in the cell.
The Golgi apparatus works closely with the other organelle, endoplasmic reticulum (ER). When a protein is created in the ER, a transition vesicle is made. The transition vesicle or sac floats through the cytoplasm containing the protein. It floats all the way to the Golgi apparatus. After the Golgi apparatus is done with modifying the protein, a secretory vesicle is then created and released. This secretory vesicle then floats to the cell membrane wherein the molecules are released out of the cell.
