Concepts Used:
Pteridophytes
Pteridophytes are the first terrestrial vascular plants. Carolus Linnaeus classified them under the group cryptogamae. Pteridophytes occupy a transitional position between bryophytes and spermatophytes.
For Example, Silver fern, Equisetum, Selaginella
The general characteristics of Pteridophytes are:
- They are seedless.
- They are multicellular.
- They reproduce through spores.
- They are independent and free-living organisms.
- They have a well-differentiated plant body into root, stem and leaves.
