Hello Student

Alternation of generation:
Haploid gametophytic and spore producing sporophytic generation alternate with each other in this process.
Haplontic:Gametophytic phase dominant. e.g., Chlamydomonas
Diplontic: Sporophytic phase dominant. e.g., Angiosperms and Gymnosperms
Haplo-Diplontic: Intermediate like stage where gametophytic and sporophytic stage partially dominates at different stages. e.g., Bryophytes and Pteridophytes.
