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 botanical snakes?
Botanical snakes is not a scientifically recognized term. It might refer to plants that have snake-like characteristics in their appearance, such as twisted or winding stems or leaves.
What is the living fossil among the pteridophytes?
equisetum
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)
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.
Discuss the stelar evolution in pteridophytes?
In pteridophytes, or ferns and their relatives, stelar evolution reflects adaptations to terrestrial life. The primary types of steles found in pteridophytes include protosteles, siphonosteles, and eusteles, with protosteles being the simplest and most primitive form. As pteridophytes evolved, the complexity of their stelar structures increased, allowing for more efficient conduction of water and nutrients. This evolution facilitated their diversification in various habitats, contributing to their success as vascular plants.
What is botanical term for plant that reproduces by spores?
ferns PTERIDOPHYTES
