The dominant, photosynthetic phase in the life cycle of a bryophyte is the:

Answer: gametophyte.

  • A gametophyte
  • B the sporophyte
  • C the zygote
  • D the seed

Correct answer: A. gametophyte

Explanation: In bryophytes the haploid gametophyte is the dominant, green phase.

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.
