Pteridophytes are vascular plants that reproduce via spores and include three main groups: ferns, horsetails, and clubmosses. Ferns are characterized by their broad, feathery leaves known as fronds. Horsetails have jointed stems and are often found in wet environments, while clubmosses resemble small conifers and have a more primitive structure. Each group exhibits unique reproductive and morphological traits that distinguish them within the pteridophyte category.

What are the major groups of plantae?
The major groups of Plantae are bryophytes (mosses, liverworts, and hornworts), pteridophytes (ferns and horsetails), gymnosperms (conifers, cycads, ginkgoes), and angiosperms (flowering plants). Each group has unique characteristics and reproductive strategies.
What are the four groups of terrestrial plants?
The four groups of terrestrial plants are bryophytes (mosses and liverworts), pteridophytes (ferns and their relatives), gymnosperms (conifers and cycads), and angiosperms (flowering plants). These groups vary in their reproductive structures and evolutionary history.
What is the difference between pteridophytes and gymnosperms?
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.
What are the three main groups of seedless vascular plants?
Here are a few:Seedless Non vascular Plants:Bryophytes:MossesLiverwortsHornwortsSeedless Vascular Plants:LycophytesClub MossesSpike MossesQuil MossesPterophytesFernsWhisk FernsHorsetails
What are examples of pteridophytes?
Selaginella and Dryopteris .
What is the living fossil among the pteridophytes?
equisetum
What gruops are ferns in?
Ferns belong to pteridophytes
Why are angiosperms closely related to pteridophytes?
gymnosperms
Do pteridophytes have flowers?
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 what mya?
The first pteridophytes appeared around 400 million years ago during the Silurian period.
How do pteridophytes differ from phanerogams?
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)
Why pteridophytes have got this name?
Pteridophytes are named for their distinctive reproductive structures, specifically the presence of fronds (leaves) that resemble feathers, derived from the Greek word "pteron," meaning "wing" or "feather." This group includes ferns, horsetails, and lycophytes, which reproduce via spores rather than seeds. The name reflects their unique morphology and reproductive strategy, setting them apart from other plant groups.
