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)
These plants belong to a group called "pteridophytes." Pteridophytes are non-flowering vascular plants that reproduce using spores. They have specialized tissues for conducting water and nutrients throughout the plant body.
Pteridophytes are a group of vascular plants that reproduce via spores. They include ferns, horsetails, and club mosses. These plants have well-developed vascular tissues for conducting water and nutrients.
Comparative study of the plant groups show that the bryophytes have forms more complex than the algae but they are less developed than the pteridophytes although there is a tendency of differentiation of the gametophytic body which is not found in the pteridophytes
Strictly speaking all plants, for without water plants die! However algae, bryophytes (mosses and liverworts) and pteridophytes (ferns) all have motile male gametes which require free water to swim through to the female gamete.
Pteridology is the scientific study of ferns and related plants, known as pteridophytes. This field involves the classification, identification, distribution, ecology, and evolutionary history of these plants. Pteridologists may also study the reproductive biology and morphology of ferns.

Phanerogams are a group of plants that produce seeds, including gymnosperms (such as conifers) and angiosperms (flowering plants). They are characterized by their ability to reproduce through seeds enclosed in a protective structure.
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.
Selaginella and Dryopteris .
equisetum
gymnosperms
Ferns belong to pteridophytes
The first pteridophytes appeared around 400 million years ago during the Silurian period.
Hibiscus belongs to the division Phanerogams. Thus, it is a vascular plant.
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.
