Detailed explanation-1: -Plumule is the essential part of the seed embryo which further develops into the shoot of the plant. The plumule of the seed emerges out of the soil and develops young leaves and stems. The main parts of the plumule are epicotyl, the young leaves and the apical meristematic tissue of the shoot.

Detailed explanation-2: -The radicle grows from the micropyle of the seed and develops further down into the soil. As it grows into the soil, it starts to absorb water from it for the growth and development of the embryo. After the emergence of the radicle, the plumule comes out from the seed.

Detailed explanation-3: -The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure.
