Question

Match List-I with List-II

List-I	List-II
(A) Centriole	(I) Thylakoids
(B) Chlorophyll	(II) Infoldings in mitochondria
(C) Cristae	(III) Nucleic acids
(D) Ribozymes	(IV) Basal body cilia or flagella

Choose the correct answer from the options given below

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

Hint:

To solve this quickly, associate Ribozymes with nucleic acids (since they are catalytic RNA, D-III) and Cristae with mitochondria (C-II). This immediately isolates the correct option.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This matching problem requires connecting specific cellular structures, organelles, or biomolecules with their physiological locations, structures, or biochemical classifications.

Step 2: Detailed Explanation:
Let us analyze each item and match them:

A. Centriole: Centrioles are cylindrical structures made of microtubules. They organize the microtubule assembly that forms the basal body of cilia and flagella in eukaryotic cells. Thus, (A) matches with (IV).

B. Chlorophyll: Chlorophyll is the green photosynthetic pigment located within the thylakoid membranes of chloroplasts, where light absorption occurs. Thus, (B) matches with (I).

C. Cristae: Cristae are the highly folded structures of the inner mitochondrial membrane that house the electron transport chain and ATP synthase complexes. Thus, (C) matches with (II).

D. Ribozymes: Ribozymes are specialized RNA molecules that have catalytic activity, meaning they are nucleic acids that act as enzymes. Thus, (D) matches with (III).
This gives the combination: (A) - (IV), (B) - (I), (C) - (II), (D) - (III).

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