Q74.Match List I with List II
LIST I
A. Labyrinth seeds
B. Anemochory
C. Autochory
D. Diplospory
LIST II
I. Ecballium elaterium
II. Antennaria alpina
III. Kingiodendron
IV. Oroxylum indicum
Choose the correct answer from the options given below:
(1) A–II, B–I, C–III, D–IV
(2) A–IV, B–III, C–II, D–I
(3) A–III, B–IV, C–I, D–II
(4) A–I, B–II, C–IV, D–III
The correct option is (3) A–III, B–IV, C–I, D–II.
Detailed Matching Explanation
These terms relate to seed dispersal and apomixis in botany:
-
A. Labyrinth seeds → III. Kingiodendron: Labyrinth seeds have intricate, maze-like seed coat sculpturing for water impermeability and dispersal; characteristic of Kingiodendron pinnatum (Fabaceae).
-
B. Anemochory → IV. Oroxylum indicum: Wind dispersal (anemochory); Oroxylum indicum (Bignoniaceae) has winged fruits/seeds that spin and glide in wind.
-
C. Autochory → I. Ecballium elaterium: Self-dispersal (autochory/ballochory); squirting cucumber explodes, ejecting seeds explosively up to 10m via hydrostatic pressure.
-
D. Diplospory → II. Antennaria alpina: Aposporic apomixis where diploid embryo sac forms from megaspore mother cell without meiosis; seen in Antennaria (Asteraceae).[prior biology context]
Option Analysis
Labyrinth seeds anemochory autochory diplospory matching tests seed dispersal mechanisms and apomixis—key for NEET plant physiology and reproduction.
Core Concepts
-
Labyrinth seeds: Reticulate seed coat for hydrochory resistance (Kingiodendron).
-
Anemochory: Wind-aided dispersal via wings/samaras (Oroxylum).
-
Autochory: Explosive self-ejection (Ecballium elaterium‘s squirting).
-
Diplospory: Diploid gametophyte formation without reduction (Antennaria).[prior]
