The Zoopagomycotina are a subdivision (incertae sedis) of the fungal division Zygomycota sensu lato. [1] It contains 5 families and 20 genera. [2] Relationships among and within subphyla of Zygomycota are poorly understood, and their monophyly remains in question, so they are sometimes referred to by the informal name zygomycetes.
The name Zygomycota refers to the zygosporangia characteristically formed by the members of this clade, in which resistant spherical spores are formed during sexual reproduction. Zygos is Greek for "joining" or "a yoke ", referring to the fusion of two hyphal strands which produces these spores, and -mycota is a suffix referring to a division ...
The zygosporangium is a unique structure to the Zygomycota and is easily recognizable in microscopy due to its characteristic dark color and spiky shape. The nuclei join in a process called karyogamy to form a zygote, which grows into a mature diploid zygomycete. A diploid zygomycete can then undergo meiosis to create spores, which disperse and ...
[1] [2] Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae , there are two multicellular stages, and the life cycle is referred to as alternation of generations .
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. [1] Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection.
A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists.Zygospores are created by the nuclear fusion of haploid cells. In fungi, zygospores are formed in zygosporangia after the fusion of specialized budding structures, from mycelia of the same (in homothallic fungi) or different mating types (in heterothallic fungi), and may be chlamydospores.

In most species, gonads are paired organs of similar size, which can be partially or totally fused. [1] There may also be a range of secondary organs that increase reproductive fitness. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm or eggs are released; the sex of a fish can often be determined ...
Mucoromycota is a division within the kingdom fungi. [1] It includes a diverse group of various molds, including the common bread molds Mucor and Rhizopus. [2] It is a sister phylum to Dikarya.
