Q. 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 wind, water and germinate and animals in different environments. This fact contributes to the exploration for the diversity of plant species and of a variety of ecological niches.
Seeds in addition protect the plant embryo against external aggressions and they also provide germination under more satisfactory conditions (inside the seed). These characteristics contribute to the evolutionary accomplishment of the phanerogam.
