___are called as amphibians of the plant kingdom

Bryophytes

Explanation

They are known as amphibians of the plant kingdom because these plants live in soil but they need water for asexual reproduction.

  • The plant body is thallus like, i.e. prostrate or erect
  • It is attached to the substratum by rhizoids, which are unicellular or multicellular
  • They lack true vegetative structure and have a root-like, stem-like and leaf-like structure
  • Plants lack the vascular system (xylem, phloem)
  • Bryophytes show alternation of generation between independent gametophyte with sex organs, which produces sperm and eggs and dependent sporophyte which contains spores
  • The dominant part of the plant body is gametophyte which is haploid
  • The thalloid gametophyte is differentiated into rhizoids, axis and leaves
  • The gametophyte bears multicellular sex organs and is photosynthetic
  • The antheridium produces antherozoids, which are biflagellated
