There are three structures that appear from the seed: the radical, the hypocotyls and the plumule. The first structure to appear from the seed is the radical, which is the root and grows downward into the soil.
The Hypocotyl is the part of the stem closest to the seed in a young plant.
the stem
The part of the plant embryo that becomes the lower stem of the plant is called the hypocotyl. It is the region between the cotyledons (seed leaves) and the radicle (embryonic root) and plays a crucial role in anchoring the plant and supporting its growth.
It is the part of the seed that develops into the stem.
The part of the seed that has the beginnings of a root, stem, and leaves is called the embryo. This part of the seed contains all the genetic information needed for the plant to develop and grow.

the stem
It starts as a seedling. Then it becomes a stem. Next it grows leaves. Finally it becomes a plant!
The primary root emerges first from an acorn seed during germination. It is responsible for anchoring the seedling in the soil and absorbing water and nutrients.
The part of the pllant in the soil is mostly the seed and when the seed grows it will be also the roots but the stem and rest of the plant would be out of the ground.
