Question

The principal function of Golgi apparatus is
(A) Producing enzymes
(B) Protein synthesis
(C) Synthesis of lipids
(D) Packaging materials

Answer 1

Hint: Golgi apparatus is also known as Golgi bodies or Golgi. It is the organelle which is found in most of the eukaryotic cells. It is found in the cytoplasm near the nucleus and the centrosome in the cell. It is called the manufacturing and the shipping center of the cell.

Complete Answer:
It has many series of flat pouches called cisternae. And this cisternae is known as the functional unit of the Golgi apparatus. Each Golgi mostly contains six to eight cisternae in them. The main function of the Golgi bodies is to sort, modify and transport the proteins and the lipids which are synthesized within the cells. Golgi apparatus converts all the protein into the membrane bound vesicles before they send to the other parts of the body.

They modify the protein by packing the proteins into the transition vesicles produced by the endoplasmic reticulum before they leave the cell to reach its destination by transporting through the blood. It not only modifies the proteins, lipids are also transported by it. Hence the principle function of Golgi apparatus is packaging materials.

Thus the option (D) is correct.

Note: They also have the other important functions like transportation of the lipids throughout the cell and synthesis of the lysosomes. The lysosomes help in the production of digestive enzymes which digest food particles, dead cells, microorganisms etc.
