Question

Match List-I with List-II

List-I (Cell organelle)	List-II (Functions)
(A) Vacuole	(I) Respiration
(B) Mitochondria	(II) Photosynthesis
(C) Chloroplast	(III) Protein synthesis
(D) Ribosomes	(IV) Accumulation of toxic materials

Choose the correct answer from the options given below

• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

To solve matching questions quickly, find the most obvious pair first. For instance, matching Chloroplast with Photosynthesis (C-II) and Mitochondria with Respiration (B-I) immediately narrows down the choices to the correct option.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This question requires matching different eukaryotic cell organelles with their primary physiological and metabolic functions.

Step 2: Detailed Explanation:
Let us analyze each organelle and its corresponding function:

(A). Vacuole: The central vacuole of a plant cell functions as a storage compartment for water and nutrients, and also acts as a repository to isolate metabolic by-products and toxic materials (such as heavy metals or secondary metabolites) away from the cytoplasm. Thus, (A) matches with (IV).

(B). Mitochondria: Mitochondria are the sites of aerobic respiration, including the citric acid cycle and oxidative phosphorylation, which generates ATP. Thus, (B) matches with (I).

(C). Chloroplast: Chloroplasts contain chlorophyll pigments and are the sites of photosynthesis, converting solar energy into chemical energy (sugars). Thus, (C) matches with (II).

(D). Ribosomes: Ribosomes are the cellular machinery responsible for translating genetic information from mRNA into polypeptide chains during protein synthesis. Thus, (D) matches with (III).
This gives the correct combination: (A) - (IV), (B) - (I), (C) - (II), (D) - (III).

Step 2: Final Answer:
The correct option is (A).
