Choose the incorrect option for haplontic life cycle
1 Sporophytic generation is represented only by the one-celled zygote
2 There are no free-living sporophytes
3 The haploid spores divide mitotically and form the gametophyte
4 All are correct
Explanation:
Sporophytic generation is represented only by the one-celled zygote. There are no free-living sporophytes. Meiosis in the zygote results in the formation of haploid spores. The haploid spores divide mitotically and form the gametophyte.
