Detailed explanation-1: -Bryophytes are called amphibians of the plant kingdom because these plants need both water and soil for their survival. These plants though live in soil but they need water for sexual reproduction. The sperm of bryophyte(antherozoids) are flagellate and need water to swim to the eggs.

Detailed explanation-2: -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.

Detailed explanation-3: -Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface (e.g., their leaves).

Detailed explanation-4: -Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins.
