NTA AbhyasNTA Abhyas 2020Plant Kingdom

Solution:

Spermatophyta are seed-bearing plants which include gymnosperms and angiosperms. In spermatophyte, the type wherein the diploid sporophyte is the dominant, photosynthetic, independent phase of the plant. The gametophytic phase is represented by the single to few-celled haploid gametophyte. This kind of life cycle is termed as diplontic. An alga, Fucus sp., represents this pattern. In addition, all seed bearing plants i.e., gymnosperms and angiosperms, follow this pattern with some variations, wherein, the gametophytic phase is few to multi-celled.
