Webmeg·a·ga·me·to·phyte (mĕg′ə-gə-mē′tə-fīt′) n. The female gametophyte that arises from a megaspore of a heterosporous plant. In angiosperms, the megagametophyte is the embryo sac. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 2016 by Houghton Mifflin Harcourt Publishing Company. A gametophyte is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which …

WebJun 13, 2024 · The gametophyte is a haploid organism, containing only one set of DNA. The gametes, therefore, are produced via mitosis. When these gametes fuse, they create a zygote, which is a new diploid organism. This zygote will grow up into the sporophyte generation. The sporophyte generation is responsible for producing spores. WebDuring gametophyte development, endosporic gametophytes are dependent on their sporophyte parent. The development of the gametophyte within the spore wall directly reduces the environmental impacts on the gametophytic gene expression resulting in higher genetic variation and rates of diversification.
