Question

Golgi body originated from
(a) Lysosome
(b) Endoplasmic reticulum
(c) Mitochondria
(d) Cell membrane

Answer 1

Hint: Golgi apparatus is an organelle found in most eukaryotic cells and is part of the endomembrane system in the cytoplasm. Golgi bodies appear as stacks of flattened membrane sacs also known as cisternae. It consists of tubules, vesicles, and vacuoles.

Complete answer:
The Golgi body is part of the endomembrane system which includes the endoplasmic reticulum, Golgi apparatus, lysosome, and plasma membrane. This apparatus packages proteins into membrane- bound vesicles inside the cell. Golgi bodies receive material from the cytosol and endoplasmic reticulum in the form of vesicles. These vesicles move to the forming face of the Golgi bodies and fuse there with existing cisternae and help in the growth of the organelle.
Endoplasmic reticulum bud off the vesicular cluster which later forms the series of counterparts of the Golgi apparatus. Therefore the Golgi body originates from the endoplasmic reticulum.

So, the correct answer is the ‘endoplasmic reticulum.’

Additional Information:
- Golgi apparatus has been identified in 1897 by the Italian scientist Camillo Golgi and was named after him in 1898.
- A mammalian cell typically contains 40- 100 stacks of cisternae. Four to eight cisternae are usually present in one stack.


Note:
- Proteins synthesized in the ER are packaged into vesicles which then allowed fusing with the Golgi apparatus.
- These proteins are modified and destined for secretion.in this sense it can be thought of as similar to the post office.
- It packages and labels items which are then sent to different parts of the cell.
- The Golgi body is also involved in lipid transport and lysosome formation.
