The seed contains only DNA for the plant body and small roots. when activated by water and warmth. The seed will put out roots to become established.
Seed plants have both roots and stems. Roots anchor the plant in the ground and absorb water and nutrients, while stems support the plant and transport water and nutrients between roots and leaves.

No, seed plants do not produce rhizoids. Rhizoids are small, hair-like structures found in non-vascular plants like mosses and liverworts, and they play a role in anchoring the plant to the substrate and absorbing water and nutrients. Seed plants have roots that perform similar functions but are more complex in structure.
Integuments are modified to form the seed coat but hardening is not essential.
Some characteristics of seed plants are that they produce seeds to protect and nourish sporophytes, and the sperm of seed plants do not need water to get to the egg. Pollen can be transported by wind, human, or animals. Another characteristic is the gametophytes are small and form within the reproductive structure of the sporophytes.
The RADICLE in a seed will become the plants roots.
Yes, many seed plants do have roots and stems. However, they do not have them initially, but they do grow them eventually.
Yes they do
Seed plants have both roots and stems. Roots anchor the plant in the ground and absorb water and nutrients, while stems support the plant and transport water and nutrients between roots and leaves.
Seeds need roots because the soil sucks the water and the roots take it A seed does not need roots until it germinates and then as it has become a seedling it requires roots to survive.
Seed plants have roots, stems, leaves, has vascular tissue, and flowers that produce seeds.

Germination
Seed plants became adapted to the environment with our great climate. :)
Either they don't or they spread by roots or cuttings.
A person can determine how deep to plant a seed by reading the back of the seed packet. Generally, plants with longer roots will have to be planted further into the ground.
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.
