Known reproduction states of Mucoromycota are zygospore production and asexual reproduction. Zygospores can have decorations on their surface and range up to several millimeters in diameter. [ 13 ] Asexual reproduction typically involves the production of sporangiospores or chlamydospores . [ 3 ]
Mucor mucedo reproduction occurs in asexual and sexual methods. Mucor mucedo is also influenced by light, as cultures grown during the day at 20 °C mainly produced tall sporangiophores, rarely producing short sporangiophores or none at all. [16] Cultures drown in the dark grew a dense layer of short sporangiophores with occasional tall ones. [16]
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

Mucor is a microbial genus of approximately 40 species of molds in the family Mucoraceae. [ 1 ] [ 2 ] Species are commonly found in soil , digestive systems , plant surfaces, some cheeses like Tomme de Savoie , rotten vegetable matter and iron oxide residue in the biosorption process.
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...
The fungi imperfecti or imperfect fungi are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. They are known as imperfect fungi because only ...
Initially, Adelbert von Chamisso (studying salps, colonial marine animals between 1815 and 1818 [10]) and Japetus Steenstrup (studying the development of trematodes in 1842, and also tunicates and cnidarians) described the succession of differently organized generations (sexual and asexual) in animals as "alternation of generations". [11]
Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like structure known as a sporocyst or into rediae, either of ...
