Significance of the emergence of the seeds

Question

Specify the evolutionary significance of the emergence of the seeds in plant kingdom?

Answer 1

The evolutionary significance of seed is related to plant ability of distant colonization and to the protection of embryo. Embryo-containing seeds may be carried through the wind, water and animals and germinate in various environments. This fact contributes for exploration of the variety of ecological niches and for the diversity of plant species. In addition, seeds protect the plant embryo from the external aggressions and they too provide the germination under more enough conditions (within the seed). These characteristics contribute to the evolutionary success of phanerogam.
