Which kind of life-cycle pattern is exhibited by seed-bearing plants?

Question

Verified by Toppr

Answer 1

In a diplontic life cycle, the dominant free-living phase is the diploid (2n). The sporophyte is photosynthetic. The gametophytic phase is represented by single to few-celled haploid gametophyte. All seed-bearing plants, i.e., gymnosperms and angiosperms exhibit this type of life cycle.
So the correct option is B.
