Abstract:

Evolution of the land plants was the very significant step in the development of the life. Early plants were aquatic in the nature, they were adapted to the only aquatic habitats. It was the very long evolutionary step for the development of the life on the earth: migration of the aquatic life on the land. For this development a number of the organs appears and disappears in the course of evolution (progressive and the retrogressive evolution). For the adaptation towards the land habitat a number of the modifications occur in the structures of the organism. In this series development of the vascular system was the very important aspects in the evolution of the life on the planet. Stele development was the very first step in the evolution of the vascular system. From algae to the higher spermatophytes one can see the whole development of the vascular system. Due to the vascular system and its complexity plants are able to adjust in the harsh conditions.
