Why Do Seed Plants Have Reduced Gametophytes at Juan Pate blog

Why Do Seed Plants Have Reduced Gametophytes. in the seed plants, the size and duration of the gametophyte stage have been reduced even further, to only a few cell divisions. some gametophytes will land on a female cone. although many factors contributing to gametogenesis have been identified in flowering plants, the extreme reduction of. the character and relative extent of the two phases vary greatly among different groups of plants and algae. The pollen tube grows from the pollen grain slowly, and the generative cell in the pollen grain divides into two sperm. consequently, seed plants with the pollen tube do not have flagella on male gametes; Over the course of evolution, the gametophyte stage has become progressively reduced. the trend to gametophyte reduction continued in the lineage of vascular plants that led to seed plants. unlike the life cycles described previously, the reduced gametophytes of seed plants do not give rise to multiple.
