Describe The Alternation Of Generations In Plants. Alternation of generations is sexual reproduction in plants as it involves the creation and combining of sex cells. The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. Seed plants • about 95% of all plants, including all seed plants, have a dominant sporophyte generation in their life cycle • the evolution of pollen, produced by the sporophyte, was a key step in the adaptation of seed plants to dry land. The sexual generation in plants produces gametes, or sex cells and is called the gametophyte generation.

This can be compared to the sexual reproduction in animals where both haploid and diploid cells are found in every generation. In vascular plants, the diploid stage produces seeds. The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. When someone plants land with a particular type of plant or crop, they put plants, seeds, or young trees into the land to grow them there. The other form is haploid with only one set of chromosomes: Make sure you describe which generation is diploid and which generation is haploid.

Alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. In vascular plants, the diploid stage produces seeds. Throughout the plant life cycle, all plants undergo the alternation of generations. They germinate on the ground into a gametophyte which produces haploid male and female gametes. This can be compared to the sexual reproduction in animals where both haploid and diploid cells are found in every generation.
