In contrast to gametogenesis in animals, a gametangium is a haploid structure and formation of gametes does not involve meiosis. In contrast to gametogenesis in animals, a gametangium is a haploid structure and formation of gametes does not involve meiosis. Female gametangia provide the site for fertilization. Archegonia), from the ancient greek (beginning) and (offspring), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. In contrast to gametogenesis in animals, a gametangium is a haploid structure and formation of gametes does not involve meiosis. Gametangial contact refers to sexual reproduction where the gametangia of two different sex do not fuse or loose there identity. The numbers of nuclei entering the oogonial initials are greater than the numbers of mature uninucleate haploid female gametes, which in turn are more numerous than the numbers of zygotes in the oogonium. Gametangia) is an organ or cell in which gametes are produced that is found in many multicellular protists, algae, fungi, and the gametophytes of plants. Gametangium the organ in which the gametes are produced in lower plants. Gametangia) is an organ or cell in which gametes are produced that is found in many multicellular protists, algae, fungi, and the gametophytes of plants.
