Selaginella and Dryopteris .
Pteridophytes can be found in various habitats, including moist forests, wetlands, and along stream banks. They prefer environments with high humidity and ample water availability for reproduction through spores. Common examples of pteridophytes include ferns, horsetails, and clubmosses.
Stem of gymnosperm is aerial.Stem of pteridophytes are mostly underground.Tree Ferns have long aerial stems but these are Pteridophytes. The real difference is that gymnosperms bear seeds pteridophytes are without seeds.

Ferns belong to pteridophytes
No, pteridophytes do not have flowers. They are non-flowering vascular plants that reproduce via spores instead of seeds, and they include ferns, horsetails, and clubmosses. Pteridophytes have distinct structures like fronds and strobili but lack the reproductive structures associated with flowering plants.
The first pteridophytes appeared around 400 million years ago during the Silurian period.
Pteridophytes have naked seeds called 'Spores'. It is a Cryptogammae as reproductive organs are not visible at all. Phanerogams have seeds which store food. Reproductive organs are visible. (Flowering Parts or Cones)
Pteridophytes are non-flowering vascular plants that reproduce by spores. They have well-developed roots, stems, and leaves, with xylem and phloem for nutrient transport. Most pteridophytes require moist environments for growth and reproduction.
No, pteridophytes do not have seeds. They reproduce via spores, which are released from structures called sporangia on the underside of their leaves. These spores develop into gametophytes that produce eggs and sperm for fertilization.
In pteridophytes, or ferns and their relatives, stelar evolution reflects adaptations to terrestrial life. The primary types of steles found in pteridophytes include protosteles, siphonosteles, and eusteles, with protosteles being the simplest and most primitive form. As pteridophytes evolved, the complexity of their stelar structures increased, allowing for more efficient conduction of water and nutrients. This evolution facilitated their diversification in various habitats, contributing to their success as vascular plants.
