Question

Pteridophytes are more advanced than bryophytes in having

• A. Swimming antherozoids
• B. Sporophyte as dominant phase
• C. Archegonia
• D. Gametophyte as dominant phase

Answer 1

The correct option is B Sporophyte as dominant phase

Pteridophytes are vascular plants. In vascular plants, the sporophyte is the dominant phase. The zygote develops into sporo­phyte by mitosis that further forms the spo­rangia. The sporangia produce haploid spores through meiosis. These spores will undergo germination to give rise to hap­loid gametophytes. Thus the correct answer is option B.
