Expert Answer
- In case of bryophytes the gametophyte and sporophyte are dependent on each other. Bryophytes have the plant body as haploid gametophyte. It requires immersion in surface water for conduction and movement of sperms. The sprophyte (foot, seta and capsule) is lodged on the gametophyte:
- But in pteridophytes the gametophyte and sporophyte establish as separate plants. The gametophyte is a surface-water-dependent like the bryophytes. The sporophyte is a typical vascular plant drawing soil water through true roots.
- Hence, although bryophytes and pteridophytes both grow on soil and require water for fertilization, only bryophytes are called amphibians of plant kingdom.
