Sporophytic and gametophytic
WebCorrect option is A) Pteridophytes shows alternation of generation. They exhibit dominant sporophytic generation with an inconspicuous gametophytic generation. The sporophyte is differentiated into root, stem, and leaves. Whereas, the small and inconspicuous gametophyte is independent and autotrophic. Thus, the correct answer is option A.

WebThese haploid zoospores give rise to gametophytic plants. The gametophyte may be alike morphologically with the sporophyte as in isogeneratae or may be dissimilar with that of sporophyte as in heterogeneratae. The gametophyte then produces either iso- or aniso gametes or antherozoid and egg.
Web11 Jun 2004 · Gametophytes and sporophytes differ morphologically and functionally. The major function of diploid sporophyte generation is to produce haploid spores, which are the products of meiosis.
