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?

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
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)
What are some characteristics of pteridophytes?
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.
Do Pteridophytes have seeds?
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.
