Question

How many components are present in fully developed Golgi apparatus?

• A. 2
• B. 3
• C. 4
• D. 6

Answer 1

The correct option is C 4

The Golgi apparatus is made up of a series of compartments consisting of two main networks: the cis-Golgi network (CGN) and the trans-Golgi network (TGN). They described the Golgi complex comprising the following four components : Cisternae, vacuoles, vesicles and tubules.

1. Cisternae : These are flattened sacs arranged parallel to each other. Each cisternae is bound by a smooth membrane. Each stack of cisternae is a polarized structure having two faces; proximal or forming face and distal or maturation phase.

2. Golgian vacuoles : These are rounded sac-like structures with large space. They are formed at the distal ends of cisternae by the process of vesiculation of cisterna sacs.

3. Vesicles : They are present at the periphery of cisternae attached to tubules. They are minute droplets like in shape. These are of two types: smooth vesicle and coated vesicle.

4. Tubules: It is a network of fine branched tubular structures.
