Explain the haplo-diplontic condition in bryophytes and pteridophytes.
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Haplo-diplontic life cycle features both multicellular haploid and diploid phases:
In Bryophytes:
- Dominant phase: Independent, photosynthetic gametophyte (haploid)
- Sporophyte: Dependent on gametophyte for nutrition; consists of foot, seta, and capsule
In Pteridophytes:
- Dominant phase: Independent, vascularized sporophyte (diploid)
- Gametophyte (prothallus): Small, independent but short-lived, haploid structure
