Botany - Plant Kingdom Question with Solution | TestHub

The diploid sporophyte is represented by a dominant, independent, photosynthetic, vascular plant body. It alternates with multicellular, saprophytic/autotrophic, independent but short-lived haploid gametophyte. Such a pattern is known as haplo-diplontic life cycle. All pteridophytes exhibit this pattern. Interestingly, while most algal genera are haplontic, some of them such asEctocarpus,Polysiphonia, kelps are haplo-diplontic.
