Question

Pteridophytes‌ ‌are‌ ‌vascular‌ ‌cryptogams.‌ ‌Reason‌ ‌out‌ ‌in‌ ‌short.‌

Answer 1

Hint: Cryptogam reproduces by spores, and without any type of flowers. “crypto” means “hidden” and “Gamos” means marriage referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing of plants. It is called other names such as “thallophytes”, and “lower plants” or “spore plants” are also used occasionally. The cryptogams are at a one time they formally recognized as a group with the help of the plant kingdom.

Complete answer:
Pteridophytes: -
It is a vascular plant that disperses the spores. Because that produces neither seeds nor flowers and sometimes, they are referred to as “cryptogams”, that means their reproduction is hidden. They are free spore vascular plants and they also have a life cycle with alternating, and free-living gametophyte and sporophyte phases which are independent at maturity. Most importantly their stem is aerial or underground. Their other most common characteristics which include the vascular plant are plant plesiomorphy and apomorphy.

Vascular cryptogams: -
This type of plant is also known as or often called Tracheophytes and they are thought to represent which is a natural group so that they can each other's closest relatives and they all are descendants from a most common ancestor. The vascular cryptogams belong to the pteridophyte family.

Note:
Gymnosperms and the angiosperms are also known as phanerogams because they all have a differentiated reproductive tissue and which is helpful in the embryo and storing of food. The embryo of them is developing into seeds so this type of group is called “cryptogams”.
