Which of the following develops into a seedling under appropriate conditions?

Correct option is A

The correct answer is (A) "Embryo".

• Seeds contain an embryo that, when nurtured under ideal circumstances, matures into a seedling. The endosperm found inside seeds aids in the formation and expansion of the embryo.
• It has stored nutrition, starch, which enables the embryo's quick growth. Oil is also stored there.
• A seedling is a juvenile sporophyte that has emerged from a plant embryo.
• The germination of the seed initiates the growth of the seedling.
• The radicle, hypocotyl, and cotyledons are the three primary structural components of a typical early seedling.
• Additional Information
• Endosperm- ​The majority of angiosperm seeds have endosperm. The growing embryo receives nutrients from it. Dicotyledons have fleshy cotyledons in place of the endosperm. Endosperm remains and stores nourishment in mature seeds of monocotyledons. In addition to being rich in carbohydrates, the endosperm tissue also contains proteins and lipids.
• Cotyledons- ​The substantial portion of the embryo found inside the seed is referred to as a cotyledon. When the seed germinates, the earliest and most delicate leaf appears. Given that it supplies nutrients to the many components of an embryo, it is also known as the storage unit of seed.
• Seed coat- ​The interior components of a seed are shielded by its coat. Two layers comprise the seed coat. Testa, the term for the thick outer layer, Tegmen, is the name of the innermost, thin layer. The seed is shielded from water and sunlight by a thick seed coat.
