The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction.
<h3>What is the evolutionary importance of the seed?</h3>
Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of domain for the species, competition between the newly born plant and the mother plant is also avoided.
Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.
