Since before Pteridophytes the evolution on the land was a basic and significant step, since these pants have a number of the features of the intermediate evolution. Among them fossil psilophytlaes and the lycopodiales, spenopsides presents the lines of evolution of the further spermatophytes of the gymnosperms and angiosperms.
The percentage of arbuscular mycorrhizal pteridophytes among 256 pteridophyte species distributed in Yunnan (southwest China) was found to be lower than that in angiosperms.

A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. This New Latin word is from Ancient Greek σωρός ( sōrós ‘stack, pile, heap’). In lichens and other fungi, the sorus is surrounded by an external layer.
In ferns, spores are produced in round structures called sori (sorus: singular) on the underside of pinnules. The First Forests Middle Devonian fossil trunks from Gilboa, New York provide a window into the earliest forests.
In evolution point of view, the pteridophytes get place between bryophytes and gymnosperms for the reason of phylogenetic relationship. In morphology, pteridophytes are comprised of rhizome, scale, frond, sorus, spore, and reproduce through spore. Their life cycle is comprised of gametophyte and sporophyte. Both the gametophytes and sporophytes are potential to synthesise food materials, thus

Reproduction. Like lycophytes, pteridophytes have no flowers, using spores to reproduce. The spores are produced by sporangia. All plants have sporangia in one form or another, but in ferns these can be seen in clusters, called sori (singular: sorus).

In evolution point of view, the pteridophytes get place between bryophytes and gymnosperms for the reason of phylogenetic relationship. In morphology, pteridophytes are comprised of rhizome, scale, frond, sorus, spore, and reproduce through spore. Their life cycle is comprised of gametophyte and sporophyte. Both the gametophytes and sporophytes are potential to synthesise food materials, thus

A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. This New Latin word is from Ancient Greek σωρός ( sōrós ‘stack, pile, heap’). In lichens and other fungi, the sorus is surrounded by an external layer.
