The features of mature seed crucial for storage and availability of food through out the year are:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Seed dormancy and dehydration
A mature seed has lost most of its water, and its embryo is in a resting state called dormancy. Dehydration and dormancy let seeds be stored for long periods. They can then be used as food throughout the year and to raise a crop in the next season.
(1) Seed dormancy and dehydration — Correct. Both keep the seed inactive and safe in storage.
(2) Dehydration and germination — Incorrect. Germination means the seed starts to grow. A seed that germinates cannot be stored as food.
(3) Germination and viability — Incorrect. Germination ends storage. Viability only means that the seed is alive. NCERT names dehydration and dormancy as the features that matter for storage.
(4) Germination and dormancy — Incorrect. The two work against each other. Dormancy holds growth back and germination is growth.
