Which is the dominant phase in bryophytes?

Answer: Gametophyte.

  • A Sporophyte
  • B Gametophyte
  • C Both equally
  • D Neither

Correct answer: B. Gametophyte

Explanation: In bryophytes, the gametophyte (haploid, n) is the dominant, independent phase. The sporophyte is dependent on the gametophyte for nutrition.

Plants evolved from water-dependent algae through increasingly land-adapted groups, gaining vascular tissue (Pteridophyta), then seeds (Gymnosperms), and finally fruit-enclosed seeds (Angiosperms) - each step reducing dependence on water for reproduction.

Concept context

Classification of plants from algae to angiosperms. Understanding plant diversity is essential for NEET.
