~Gymnosperms have developed over the course of its evolution, structures that solved the main limitations present in the Pteridophytes in relation to sexual reproduction, and in the terrestrial environment.
~The organisms that have adapted fully to the terrestrial environment feature adaptations in body to retain water, thus avoiding dehydration.
