The main bodu of pteridophytes is sporophytes the leaves are small as in case of sellaginella or big as in ferns the sporophytes gives rise to multicellular gametophytes by meoisis some may bear strobiili or cones they are the first to have vascular system's

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)
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 kind of plants reproduce with spores and which kind of plants reproduce with seeds?
Plants belonging to bryophytes and Pteridophytes etc. reproduce with spores and thoseof gymnosperms and angiosperms reproduce with seeds.
What are the other ways of grouping plants?
the other ways of grouping the plant are the: asexual and sexual reproduction vascular and non-vascular plants spermatophytes and plant without seeds thallopyhtes,bryophytes and pteridophytes monocot and dicot perenials,bienials and annuals angiosperm and gymnosperm
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 are botanical snakes?
Pteridophytes or gymnosperms
What gruops are ferns in?
Ferns belong to pteridophytes
What is the living fossil among the pteridophytes?
equisetum
Why are angiosperms closely related to pteridophytes?
gymnosperms
What is botanical term for plant that reproduces by spores?
ferns PTERIDOPHYTES
How do thallophytes and pteridophytes differ from each other?
yo yo
The first pteridophytes appeared around what mya?
375 mya
What are botanical snakes called?
pteridophytes can crawled like a snake on the ground
What plants are considered BOTH a vascular and non-seed plant?
Pteridophytes.
Why are gametophytes green?
Gametophytes are green only in bryophytes and pteridophytes. This is to be photosynthetic.
