2025 Cell: The Unit of LifeEndomembrane System - Golgi Apparatus Easy Question 1 of 2 in Endomembrane System - Golgi Apparatus

Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell.

Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus.
A Both A and R are true and R is the correct explanation of A
B Both A and R are true but R is not the correct explanation of A
C A is true but R is false
D A is false but R is true

The answer is A.

Solution

Both A and R are true, and Reason explains how cis-to-trans transit enables packaging and targeting.

The Golgi apparatus principally packages and modifies macromolecules. Secretory vesicles bud off from the ER and fuse with the cis (forming) face of the Golgi, traverse the cisternae where post-translational modifications occur, and are sorted into transport vesicles at the trans (maturing) face.
