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 solve this problem, we need to match each structure in List-I with its corresponding function from List-II based on biological knowledge: 

1. Filiform apparatus guides the pollen tube into the synergid. Therefore,
(A) Filiform apparatus → (III) Guides pollen tube into the synergid.

2. Tapetum provides nourishment to the pollen grains during their development. Therefore,
(B) Tapetum → (IV) Nourishes the pollen grain.

3. Exine is the outer layer of pollen grains, known for being composed of the tough substance sporopollenin. Therefore,
(C) Exine → (I) Made up of sporopollenin.

4. Funicle is the stalk that connects the ovule to the placenta in the ovary. Therefore,
(D) Funicle → (II) Attachment of ovule to the placenta.

Comparing these matches with the options provided:

Correct option: (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Answer 2

(A) Filiform apparatus

The filiform apparatus is a structure in the synergids of the embryo sac. Its function is to guide the pollen tube into the synergid. Matching Function: (III) Guides pollen tube into the synergid.

(B) Tapetum

The tapetum is a layer of cells in the anther that nourishes the developing pollen grains. Matching Function: (IV) Nourishes the pollen grain.

(C) Exine

The exine is the outermost layer of the pollen grain, made up of sporopollenin, which is a highly resistant material. Matching Function: (I) Made up of sporopollenin.

(D) Funicle

The funicle is the stalk that attaches the ovule to the placenta in the ovary. Matching Function: (II) Attachment of ovule to the placenta.

Conclusion

Based on the explanations above, the correct matching is:

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

Therefore, the correct answer is (2) (A) - (III), (B) - (IV), (C) - (I), (D) - (II).
