Answer:
1) Complete answer: Bryophyteàs are known as amphibians of the plant kingdom because these plants live in soil but they need water for asexual reproduction. ... The sperms of bryophytes swim through water to the eggs with the help of their flagella. So bryophytes are called amphibians of the plant kingdom.
2) These rhizoids may be seen as unicellular or multicellular structures. In Riccia however, rhizoids are unicellular and unbranched structures. They anchor the thallus of the plant to the substrate and usually are of two types, smooth-walled and tuberculated.
