The RADICLE in a seed will become the plants roots.
It depends on the type of seed.
Non-seed plants evolved from seed plants.
When water, warmth, and oxygen become available a seed begins to germinate.
Integuments are modified to form the seed coat but hardening is not essential.

Yes, seed plants are vascular.
The major change in Earth's climate that favored the evolution of seed plants was the transition to a drier climate. Seed plants were better adapted than non-seed plants to survive in this drier environment because seeds are a more efficient way to disperse and protect offspring in dry conditions.
Some plants have adapted to rely on fire for germination because the heat and smoke from fires can trigger the germination process by breaking seed dormancy or stimulating the release of certain chemicals in the seed coat. This adaptation allows these plants to take advantage of the open space and nutrients created by a fire to establish themselves successfully.
