Give important of alternation of generation in the life cycle of an organisms

• There is rapid multiplication as spores are normally produced in large numbers
• Spores can survive harsh conditions and germinate when conditions are favorable
• Spores leads to formation of different varieties since meiosis takes place during their formation.
• Fertilization restores diploid chromosome number. Production of gametes by mitosis ensures that the haploid gametophyte state is maintained. This maintains the plant genome.
• Alternative between gametophyte and sporophyte generations ensures that the plant colonizes different habitats in the ecosystem.
• Interdependence between gametophyte and sporophyte generation ensures existence of both generations and avoids extinction of the plant species.
