Question

Who studied the Golgi apparatus for the first time?
A. Golgi
B. George
C. Cajal
D. Koltzoff

Answer 1

Hint: Golgi apparatus is a cell organelle that is found in all living eukaryotic cells. It helps in the packaging of protein prior to secretion.

Complete answer: An Italian physician Camillo Golgi first studied the Golgi apparatus and thus the organelle named after him.
1. Golgi apparatus is known as the manufacturing and shipping centre of a eukaryotic cell.
2. It is made up of interconnecting tubules, vesicles, and cisternae.
3. Cisternae are the simplest unit of the Golgi apparatus. It is a flat plate-like a closed structure that is held in parallel bundles. Tubules are associated with vesicles.
4. There are three types of vesicles seen in the Golgi apparatus – transitional vesicle, secretory vesicle, and clathrin-coated vesicle.
5. Clathrin is a protein component that gives structural support to the vesicles.

Hence, the correct answer is option A. Golgi.

Note: The main functions of the Golgi apparatus include –
1. It plays a key role in the protein sorting mechanism.
2. It helps in the exocytosis of the zymogen, mucus, casein, thyroglobulins, collagen and tropocollagen, melanin granules, and pigments.
3. It helps in the formation of the plasma membrane, acrosome, cortical granules, the lysosome. Golgi apparatus also helps in the transport of lipids. It also helps in the production of proteoglycans.
4. In plants, Golgi apparatus help in the secretion of materials of primary and secondary cell wall such as glycoproteins, lipids, pectins, etc.
