What is the evolutionary importance of the emergence of seeds in the plant kingdom?
The evolutionary significance of the seed is related to the plant capability of distant colonization and to the protection of the embryo. Embryo-containing seeds can be carried by water, wind and animals and germinate in dissimilar environments. This fact contributes to the exploration of a several of ecological niches and for the diversity of plant species.
Seeds in addition protect the plant embryo against external aggressions and they also give germination under more adequate conditions (inside the seed). These features contribute to the evolutionary success of the phanerogam.
