Q.13 Match List I with List II
| List I (Taxonomic characters) | List II (Families) |
|---|---|
| A. Jaculators B. Caryopsis fruits C. Cyathium D. Cremocarp fruit | I. Apiaceae II. Euphorbiaceae III. Poaceae IV. Acanthaceae |
Choose the correct answer from the options given below:
- (A) – (IV), (B) – (III), (C) – (II), (D) – (I)
- (A) – (I), (B) – (III), (C) – (II), (D) – (IV)
- (A) – (I), (B) – (II), (C) – (IV), (D) – (III)
- (A) – (III), (B) – (IV), (C) – (I), (D) – (II)
Caryopsis fruits characterize Poaceae (grasses like wheat), while other traits align specifically with Acanthaceae, Euphorbiaceae, and Apiaceae. The correct matching is option (A).
Correct Answer
The right option is (A) (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
-
A. Jaculators → IV. Acanthaceae: Slingshot-like structures disperse pollen or seeds explosively in Acanthaceae (e.g., Ruellia).
-
B. Caryopsis fruits → III. Poaceae: Dry, one-seeded indehiscent fruit with pericarp fused to seed coat, typical of grasses (wheat, rice).
-
C. Cyathium → II. Euphorbiaceae: Cup-shaped inflorescence with reduced flowers, central pistillate and peripheral staminate, as in Euphorbia.
-
D. Cremocarp fruit → I. Apiaceae: Dry schizocarpic fruit splitting into two mericarps, characteristic of carrot family (e.g., coriander).
Why Option (A) Matches Perfectly
This pairing reflects standard botanical taxonomy in NCERT and NEET syllabi. Jaculators enable ballistic dispersal in Acanthaceae; caryopsis defines Poaceae grains; cyathium is Euphorbiaceae’s unique inflorescence; cremocarp is Apiaceae’s signature fruit.
Option (B) Analysis
(A)-(I), (B)-(III), (C)-(II), (D)-(IV): Incorrect. Apiaceae (I) has no jaculators (uses cremocarp wings); Acanthaceae (IV) lacks cremocarp.
Option (C) Analysis
(A)-(I), (B)-(II), (C)-(IV), (D)-(III): Wrong. Poaceae (III) produces caryopsis, not Euphorbiaceae (II, capsular fruits); Acanthaceae (IV) has no cyathium.
Option (D) Analysis
(A)-(III), (B)-(IV), (C)-(I), (D)-(II): Flawed. Poaceae (III) has caryopsis, not jaculators; Apiaceae (I) shows no cyathium; Acanthaceae (IV) lacks caryopsis.
