Question

Match List-I with List-II:

List-I (Structures)	List-II (Functions)
(A) Filiform apparatus	(III) Guides pollen tube into the synergid
(B) Tapetum	(IV) Nourishes the pollen grain
(C) Exine	(I) Made up of sporopollenin
(D) Funicle	(II) Attachment of ovule to the placenta

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is B

To resolve this issue, it is necessary to correlate each component from List-I with its respective function in List-II, utilizing biological understanding:

1. Filiform apparatus directs the pollen tube towards the synergid. Thus,
(A) Filiform apparatus → (III) Directs pollen tube to the synergid.

2. Tapetum supplies nutrients to developing pollen grains. Consequently,
(B) Tapetum → (IV) Supplies nutrients to pollen grain.

3. Exine constitutes the external layer of pollen grains, characterized by its composition of the robust material sporopollenin. Therefore,
(C) Exine → (I) Composed of sporopollenin.

4. Funicle is the pedicel attaching the ovule to the ovary's placenta. Hence,
(D) Funicle → (II) Attachment of ovule to placenta.

Evaluating these pairings against the available choices:

The correct selection is: (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
