How many components are present in fully developed golgi apparatus
A. 2
B. 3
C. 4
D. 6

Hint: Golgi apparatus is the cell organelle which is present in eukaryotic cells. It helps in packaging and transport of various molecules in the cell. The main part of the golgi body includes cisternae which are the sac like foldings. The other parts of the golgi body include tubules, vesicles and vacuoles.

Complete Answer:
Golgi complex is also called the golgi body or golgi apparatus. It is a cell organelle found in eukaryotic organisms. The main function performed by this organelle is the packaging and shipping of various molecules such as proteins and lipids.
Under the electron microscope, the structure of fully matured golgi apparatus consists of following parts-
a. Cisternae - They are the main units of the golgi body which are generally central, flat or saucer shaped forming closed compartments. They are arranged parallely forming a stack. In- between the stacks, we can find a space which is filled by various tubules. The cisternae which are present at the convex end are called as the cis or forming face whereas the cisternae at the concave end are called as the mature or trans face.

b. Tubules - They form a network of tubular structures.

c. Vesicles - These are the membrane bound structures which are of three types-
1. Transitional vesicles
2. Secretory vesicles
3. Clathrin - coated vesicles

d. Golgi vacuoles - These are round membrane bound sac-like structures. They are formed as a result of vesiculation of cisternae sacs.

Additional information: Functions of golgi apparatus:
- It helps in the packaging and transport of proteins. It receives the proteins from the endoplasmic reticulum and packages it to the various vesicles.
- Transport of lipids and formation of lysosomes.
- It is the site of synthesis for glycolipids.
- In plant cells, they help in the synthesis of polysaccharides of golgi apparatus.

Hence the correct answer is option C.

Note: The cell organelles are the cellular components of a cell which perform various functions of the cell. The function of packaging and transport of various proteins and lipid molecules is done by the golgi body or the golgi apparatus.
