Characteristics of psilopsida

Explanation:

• Psilopsida is considered as the earliest group of vascular plants. The majority of the agents of this gathering have gotten wiped out, for instance, Horneophyton, psilophyton, cooksonia  
• The Psilopsida are little, epiphytic or earthly, vascular plants which need blossoms and duplicate explicitly by spores. The herbaceous sporophyte comprises of a crawling rhizome (that needs evident roots) and an ethereal stem which is unified or dichotomously spread and has straightforward scale-like or leaf-like limbs (called 'leaves').  
• In psilopsida plants have rootless sporophytes. The stem is separated into an underground rhizome and an aeronautical part. Both are dichotomously stretched. The rhizome bears rhizoids, both play out the capacity of root. The elevated branches are green, leafless and bear little veinless out developments and complete photosynthesis.
