In angiosperms, which generation is dominant?

Answer: Sporophyte.

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

Correct answer: B. Sporophyte

Explanation: In angiosperms (and all seed plants), the sporophyte (2n) is the dominant, long-lived, conspicuous plant. The gametophyte is highly reduced: male gametophyte is pollen grain; female is embryo sac.

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.
