Answers
Answer:
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.
Answer:
Amphibians of Plant kingdom: Bryophytes are called the amphibians of the plant kingdom because they are found in moist areas and require the presence of water for fertilization. In bryophytes, true vascular system is absent, i.e., they do not have specialised tissues for the conduction of water and food materials, from one part of the plant body to another.
The plant body is commonly differentiated into root-like, stem like and leaf-like structures. They lack real roots, stems, leaves, etc. and do not bear a flower.
Sex organs are multicellular and jacketed. The sporophytes are partial parasites on the gametophytes.
In e.g., Funaria, Riccia, Mosses, Marchantia (liverwort), Anthoceros. etc
