Detailed explanation-1: -A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).

Detailed explanation-2: -Seedling: Seedling is a young plant, especially one coming out from seed and not from cutting. A seedling develops out of a plant embryo from a seed. Seedling development starts with the germination of the seed.

Detailed explanation-3: -Note: Plumule is formed in embryo at the time of germination. It helps in forming a baby plant that develops into an adult plant. It also includes stem apex and the plant’s first leaves.

Detailed explanation-4: -Plumule is the part of a plant embryo formed at the time of germination. It is the shoot of a baby plant and develops into the shoot system in adult plants. It consists of the stem apex and first leaves. So, the correct answer is ‘Plumule’

Detailed explanation-5: -The embryo begins to grow as cells elongate and divide. In the final stage, the germinating seed continues to undergo metabolic changes which transform the embryo into a seedling.
