Question

What happens when Golgi apparatus is removed from the cell?
A)Modification, sorting and packaging of the materials coming from endoplasmic reticulum or synthesized in the Golgi complex itself, will not take place.
B)Modification, sorting and packaging of the materials coming from endoplasmic reticulum or synthesized in the Golgi complex itself, takes place as usual.
C)Modification, sorting and packaging of the materials coming from cytoplasm or synthesized in the Golgi complex itself, will not take place.
D)All of the above.

Answer 1

Golgi apparatus is the membrane-bound organelle found in eukaryotic cells. It is composed of flattened, stacked pouches called cisternae.

Complete answer:
Golgi apparatus is also called Golgi complex or Golgi body. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. Many types of cells contain only one or more Golgi apparatus, plant cells can contain up to a hundred Golgi apparatus.

Golgi apparatus helps process and package proteins and lipid molecules and proteins which need to be exported from the cell. One of the functions of the Golgi is to make new vesicles out of the membrane of the Golgi apparatus and put glycoproteins and other substances into those vesicles. The vesicles which are filled with the Golgi products move to the rest of the cell.

Option A: Golgi apparatus forms the part of the cellular endomembrane system that processes the proteins coming from the endoplasmic reticulum. So when the Golgi apparatus is removed from the cell modification, sorting and packaging of the materials coming from endoplasmic reticulum or synthesized in the Golgi complex itself, will not take place. Therefore, this is the correct option.

Option B: So when the Golgi apparatus is removed from the cell the modification, sorting and packaging of the materials does not take place as usual. Therefore, this is the incorrect option.

Option C: The materials to be modified, sorted and packed do not come from the cytoplasm. Therefore, this is the incorrect option.

Option D: Since the options B and C are incorrect. Therefore, this is the incorrect option.

Hence, the correct answer is option (A)

Note: The Golgi apparatus was observed by Italian cytologist Camillo Golgi in 1897. It was discovered with the help of a special staining technique in which nervous tissue is fixed with potassium dichromate and then suffused with silver nitrate. Golgi apparatus was confirmed with the help of an electron microscope.
