Web1) When a plant changes from gametophyte to sporophyte, the life cycle shows alternation of generations and is called as haplodiplontic life cycle. In which diploid sporophyte produces haploid spores via meiosis and each spore undergo mitosis to gene … View the full answer Previous question Next question WebJan 13, 2024 · Figure 1. Alternation of generation life cycle pattern of land plants. Lower plants ( Bryophyta) spend the majority of their life in the gametophyte stage, whereas the sporophyte stage is the dominant stage in vascular plants (gymnosperms and angiosperms). Fertilization and meiosis function as ontogeny switch points.

Hornworts The hornworts (Anthocerotophyta) belong to the broad bryophyte group that have colonized a variety of habitats on land, although they are never far from a source of moisture. The short, blue-green gametophyte is the dominant phase of the lifecycle of a hornwort. WebLike all plants, the bryophyte life cycle goes through both haploid (gametophyte) and diploid (sporophyte) stages. The gametophyte comprises the main plant (the green moss or liverwort), while the diploid … WebRegular heteromorphic alternation of generation occurs in bryophytes. The gametophyte produces haploid gametes. After fertilization the oospore gives rise to diplopod sporophyte. The sporophyte produces the spores by meiosis. The spores give rise to the gametophyte. northampton government jobs
