Explain the haplo-diplontic stage. |
| Answer» Haplontic- sporophytic generation is\xa0represented by one celled zygote. There are no free living sporophytes. Meiosis in the zygotes results in the formation of haploid spores. The haploid spores divide mitotically and form gametophyte. The dominant photosynthetic phase in such plants is free living gametophyte. This kind of life cycle is haplontic.Diplontic-\xa0Diploid sporophyte is dominant photosynthetic phase. The gametophyte phase is represented by single to few celled haploid gametophyte. This kind is called diplontic.Haplo-diplontic-\xa0both phases are multicellular and exhibit an intermediate condition. They differ in their dominant phases. | |
