Is male gametophyte free living in pteridophytes?
Solution:
The gametophyte is not independent in case of gymnosperms and angiosperms. In Pinus, the gametophyte (haploid) stage depends upon the sporophyte (diploid) stage. In both bryophytes and pteridophytes, the gametophyte is the free living generation. In both bryophytes and pteridophytes, the gametophyte is the free living generation.
