Question

Are Pteridophytes Amphibians?

Answer 1

Hint: The first land flora with no proper vascular system which can stay both on land and in water are termed as Amphibians. Pteridophytes are vascular plants which disperse spores as they do not produce flowers or spores.

Complete answer:
Pteridophytes are vascular vegetation which incorporate roots, leaves and stems. These are also called cryptograms as they don't produce flowers and seeds. They comprise vascular structures (xylem and phloem). These flowers primarily include ferns, clubmosses, spike mosses, and so forth and reproduce via means of spores. Ferns, horsetails, mosses are few examples of pteridophytes. They are found in moist, shady and damp environments. They are land plants and are found in the cracks of rocks, swamps and tropical trees.

The plants which act as amphibians live on land and require water for reproduction. In case of pteridophytes, they disperse spores and require water for reproduction. But they are vascular with definite xylem and phloem so they are not the true amphibians of the plant kingdom rather they are known as vascular amphibians.

So, pteridophytes are not amphibians.

Note: Bryophytes are recognized as amphibians of the plant kingdom because these flowers live in soil however they need water for asexual reproduction. They were non-vascular plants. Asexual reproduction is the predominant technique of multiplication in bryophytes. It takes place through the production of spores. Though bryophytes live on the land, they require water for fertilization. The sperms of bryophytes swim through water to the eggs with the aid of their flagella. So bryophytes are called amphibians of the plant kingdom.
