Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Cryptogams (cryptos - hidden, gamos, marriage) are plants that do not bear conspicuous reproductive structures. Plants including algae, bryophytes and pteridophytes are cryptogams, but among them only pteridophytes have vascular tissues. Thus, they are called vascular cryptogams, while algae and bryophytes are non-vascular cryptogams.

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.
