Answer :

A. After maturation of the seed, its water content is reduced and seeds become relatively dry. The general metabolic activity of the embryo slows down. The state of inactivity seed is called seed dormancy. Dehydration (least water) and dormancy of mature seeds are crucial for storage of seeds which can be used as food throughout the year and also to grow crop in the next season.

B. Seeds provide many advantages to plants. The seeds have better adaptive strategies to occupy and grow in the new area. This is possible because they have sufficient food reserves, young seedlings are nourished until they are capable of photosynthesis on their own. The hard seed coat provides protection to the young embryo. Seeds are the products of sexual reproduction, they have new genetic combinations which lead to variations.
