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. Plants which reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations some differences exist. Plants use meiosis to produce spores that develop into multicellular haploid gametophytes which produce gametes by mitosis. The sperm are formed in an organ known as the antheridium and the egg cells in a flask-shaped organ called the archegonium. In flowering plants, the female gametophyte is produced i… fnf vs edd well well well

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. WebSpores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants. Bacterial spores serve largely as a resting, or dormant, stage in … WebFormation Of Gametes. A gamete is the male or female reproductive cell that contains half the genetic material of the organism. When two human gametes meet i.e. a sperm cell and an ovum then a zygote formation takes place which is also known as a fertilized egg. Gametes are produced by the cell division which is called meiosis. fnf vs evil bf discharge
