Question

What is Golgi apparatus made up of?
A) Cisternae
B) Tubules and Vesicles
C) Golgian vacuoles
D) All of the above

Answer 1

Hint: Try to find out the structure of the cell organelle called Golgi Bodies (apparatus) to know its constituents.The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.

Complete answer:
1) Cisternae are flattened membrane disks of the endoplasmic reticulum and Golgi apparatus. A Golgi stack may contain anywhere from three to twenty cisternae, but most contain about six cisternae.It has two faces the cis-cisternae, followed by the medial cisternae, then the trans-cisternae as they move away from the endoplasmic reticulum. It helps in the transportation of proteins and other Golgi enzymes.
2) Vesicles and tubules are examples of mesosomes. They are formed by the folding of the cell membrane. Vesicles are small, membrane-bound sacs within a cell. Vesicles may contain fluids, such as vacuoles. Vesicles may also contain enzymes that aid in the metabolism within a cell. Vesicles often aid in the transportation of materials within the cell or across the cell membrane. Tubules are small tubes that may be found in various structures or organs in the body. An example of a cellular tubule is a T tubule.
3) Golgian vacuoles refer to the expanded parts of the cisternae of the Golgi bodies which are modified to form vacuoles.
Since, the golgi apparatus comprises all these three components the answer is All of the above.

Thus, the correct answer is option D (All of the above).

Note:The golgi bodies are responsible for packaging proteins into vesicles prior to secretion and therefore play a key role in the secretory pathway. Therefore, they need all these three components for functioning.
