Question

Match List I with List II:

List I		List II
A	Axoneme	I	Centriole
B	Cartwheel pattern	II	Cilia and flagella
C	Crista	III	Chromosome
D	Satellite	IV	Mitochondria

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-II, C-III, D-I
• C. A-II, B-IV, C-I, D-III
• D. A-II, B-I, C-IV, D-III

Answer 1

The Correct Option is D

To solve the given matching problem, we need to associate items from List I with their correct counterparts in List II based on scientific understanding. Below is the detailed matching along with explanations for each pairing:

List I		List II
A	Axoneme	II	Cilia and flagella
B	Cartwheel pattern	I	Centriole
C	Crista	IV	Mitochondria
D	Satellite	III	Chromosome

A detailed explanation of each match is as follows:

• Axoneme (A): This is the central strand of a cilium or flagellum and is typical for its "9+2" arrangement of microtubules, hence matches with II (Cilia and flagella).
• Cartwheel pattern (B): This pattern is found in the structure of centrioles, which helps them in fulfilling their role in cell division, so it matches with I (Centriole).
• Crista (C): These are the foldings of the inner membrane of mitochondria, increasing the surface area for chemical reactions, thus matching with IV (Mitochondria).
• Satellite (D): These are chromosomal structures that can be seen as secondary constrictions on some chromosomes, so it matches with III (Chromosome).

Therefore, the correct matching sequence is: A-II, B-I, C-IV, D-III, which is given in the option: A-II, B-I, C-IV, D-III.

Answer 2

A. Axoneme – Found in cilia and flagella. 
Matches with: II. Cilia and flagella.

B. Cartwheel pattern – Observed in the structure of centriole. 
Matches with: I. Centriole.

C. Crista – Found in the inner membrane of mitochondria. 
Matches with: IV. Mitochondria.

D. Satellite – Refers to small bodies near chromosomes. 
Matches with: III. Chromosome.

Thus, the correct answer is (4) A-II, B-I, C-IV, D-III.
