Question

Name the cell organelle which is known as the ‘Packaging and dispatching unit of the cell’.
A. Golgi body
B. Mitochondria
C. Chloroplast
D. Ribosome

Answer 1

Hint: Organelle is the part of the cell having specialised function within a cell. Packaging and processing of proteins and lipids is one of the important functions in a cell.

Complete answer:
We all know that “cell is a structural and functional unit of life”. This single statement carries a great meaning. The whole structure of our body is made up of basic unit cells. All functions which our body performs are the result of coordinated functioning of cells. Cell itself is able to perform all these functions due to various processes going inside a cell. And that includes transcription and translation.
Proteins are synthesised inside ribosomes and polypeptides are made then post translational modifications happen to activate the proteins and send them to their active or working sites. Packaging and processing of very crucial functions as it ensures transport of proteins and lipids to their functional sites.
Let’s talk about each given option: Mitochondria is the power-house of a cell which is responsible for the production of energy in the form of ATP. Respiration takes place at mitochondria and helps in gaseous exchange.
Chloroplasts are organelles which help in respiration of plants; they are sites of food production for plants and production of oxygen as a by-product. So, chloroplasts are involved in food production and processing.
Ribosomes are organelles which help in translation of m-RNA to proteins with the help of its subunits and RNA enzymes. Ribosomes are present in free as well as bounded state. In a bounded state these are attached with a rough endoplasmic reticulum and in free form they are present in cytoplasm near the nucleus.
Golgi bodies are the structures which are responsible for the processing and transportation of proteins from site to site of action. Golgi bodies are also called tagging sites for proteins.

So, after discussion we can conclude that option A. Golgi body is the site of protein packaging and dispatching unit of cell.

Note:
Ribosomes are the unit responsible for production of proteins and Golgi bodies are responsible for packaging and tagging them for a particular site. Do not get confused in-between two. So, our answer is Golgi body.
