Answer: The diploid sporophyte.
- A The haploid gametophyte
- B The diploid sporophyte
- C A prothallus stage
- D A protonema stage
Correct answer: B. The diploid sporophyte
Explanation: In pteridophytes the dominant, visible plant is the diploid sporophyte; the gametophyte is a small, separate prothallus.
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.
