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)
Which group of plants include ferns horsetails and club mosses?
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.
How would you describe the origin of bryophytes?
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
What group of plants require water for sexual reproduction to occur?
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.
What does pteridology mean?
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.
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 examples of pteridophytes?
Selaginella and Dryopteris .
What is the living fossil among the pteridophytes?
equisetum
Why are angiosperms closely related to pteridophytes?
gymnosperms
What gruops are ferns in?
Ferns belong to pteridophytes
The first pteridophytes appeared around what mya?
The first pteridophytes appeared around 400 million years ago during the Silurian period.

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.
What is botanical term for plant that reproduces by spores?
ferns PTERIDOPHYTES
How do thallophytes and pteridophytes differ from each other?
yo yo
Why are gametophytes green?
Gametophytes are green only in bryophytes and pteridophytes. This is to be photosynthetic.
