"WebSexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

Web28 apr. 2024 · The mature haploid gametophyte then produces gametes by mitosis. This process differs from what is seen in animal organisms. In animal cells, haploid cells (gametes) are only produced by meiosis and only diploid cells undergo mitosis. In plants, the gametophyte phase ends with the formation of a diploid zygote by sexual reproduction. WebGametes produced by one type of thallus are compatible only with gametes produced by the other type. Such fungi are said to be heterothallic. Many fungi, however, are homothallic; i.e., sex organs produced by a single thallus are self-compatible, and a second thallus is unnecessary for sexual reproduction.
