Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
(A) Artificial hybridization — this matches (II) Crop improvement process. Plant breeders cross selected parents by controlled pollination to bring desired characters together in one plant. The female parent is first emasculated and bagged so that only the chosen pollen reaches the stigma.
(B) Exine — this matches (III) Sporopollenin. The exine is the hard outer wall of the pollen grain. It is made of sporopollenin, which resists high temperature, strong acids and alkalis.
(C) Xenogamy — this matches (IV) Pollination. It is a kind of pollination in which pollen from the anther of one plant reaches the stigma of a different plant. It is the only kind that brings genetically different pollen.
(D) Parthenocarpy — this matches (I) Fruits develop without fertilization. Banana is an example. The fruit forms without fertilisation, so it has no seeds.
Note: Artificial hybridization also involves pollination, so (A) could be linked with (IV) as well. But Xenogamy (C) fits only (IV), and Crop improvement process (II) is left for (A). This is why Option (4) is the only possible answer.
