FEATURES SHARED
Permission granted by Michael Farabee Features shared with Bryophyta and other Tracheophyta. Vascular seedless plants are right in between bryophytes and vascular seeded plants. Bryophytes are nonvascular plants which evolved earlier than the vascular seedless plants. Vascular seeded plants appeared even later on the evolutionary scale. Therefore, since vascular seedless plants is right in the middle of the two evolutions, they have features similar to both. According to the Annals of the Missouri Botanical Garden, the vascular seedless plants are most abundant and consistent in genotype through time and are the best for studies in patterns of plant diversification (Niklas).All three groups, nonvascular, vascular seeded and seedless, are in the Kingdom Plantae, which means that they are multi-cellular eukaryotes and also photosynthetic autotrophs. Eukaryotes differ from prokaryotes in that eukaryotes are generally multi-cellular and have a nuclear membrane. Autotrophs are organisms that produce their own food, usually through photosynthesis, which converts light energy into chemical energy. The bryophyte life-cycle is very similar to that of the vascular seedless plants. Neither of the two classes grow to a large size and they both have to live near moist environments in order to prosper. Also, some phyla of vascular seedless plants do not develop true roots, but develop rhizomes, similar to bryophytes. Vascular seedless and vascular seeded plants both have xylem and phloem to help transport nutrients and water. They are more evolved and have many more extant species.
