Question

What do you understand by alternation of generation?

Answer 1

The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations.

Sporophytic generation is represent 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. The dominant, photosynthetic phase in such plant is termed as the free-living gametophyte. This kind of life cycle is termed as haplontic. eg: Volvox, Spirogyra.
