Question

Match List-I with List-II

List-I Specialized part of cell	List-II Specialized combinations of cell
(A) Centriole	(I) Infoldings in mitochondria
(B) Chlorophyll	(II) Thylakoids
(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) - (II), (C) - (I), (D) - (III)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)

Hint:

Match each structure to its one clear textbook function before checking the options.

Answer 1

The Correct Option is A

This is a direct matching question, so the fastest way to solve it is to fix each item in List-I to its one correct partner in List-II based on basic cell biology facts, then check which option lists all four pairs correctly.

1. (A) Centriole: organizes the basal body, the structure that gives rise to cilia and flagella, so A matches (IV) Basal body cilia or flagella.
2. (B) Chlorophyll: sits inside the thylakoid membranes inside the chloroplast, so B matches (II) Thylakoids.
3. (C) Cristae: are simply the folded inner membrane of the mitochondrion, so C matches (I) Infoldings in mitochondria.
4. (D) Ribozymes: are RNA molecules that can catalyze reactions, placing them in the nucleic acids group, so D matches (III) Nucleic acids.

Putting these four pairs together gives A-IV, B-II, C-I, D-III, exactly the combination listed in option 1. None of the other three options keep all four pairs correct at the same time, each swaps at least one match, such as pairing Ribozymes with basal bodies or Cristae with nucleic acids, which does not fit the actual structures.

Let's summarize:

• Centriole links to the basal body of cilia and flagella, Chlorophyll to thylakoids, Cristae to mitochondrial infoldings, Ribozymes to nucleic acids.
• Only option 1 keeps every one of these four pairs correct together.

So the correct answer is option 1, (A)-(IV), (B)-(II), (C)-(I), (D)-(III).
