Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). 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. In the light of the above statements, choose the correct answer from the options given below:

Solution & Explanation

Answer: (C) Both A and R are true and R is the correct explanation of A Solution: Assertion is true — the Golgi apparatus principally packages materials made by the ER and delivers them to intracellular targets or secretes them outside the cell. The Reason is also true and explains exactly HOW this happens: ER-derived vesicles fuse with the convex cis (forming) face, are modified in the cisternae, and are released from the concave trans (maturing) face. Thus R correctly explains A. NCERT Reference: Ch 8, p.96, lines 13–21: "The golgi apparatus principally performs the function of packaging materials, to be delivered either to the intra-cellular targets or secreted outside the cell. Materials to be packaged in the form of vesicles from the ER fuse with the cis face of the golgi apparatus and move towards the maturing face... before they are released from its trans face."
