Sexual reproduction occurs under unfavorable conditions with the mating of compatible strains, ultimately resulting in the zygospore. Rhizopus is a type of fungus that belongs to the class Zygomycetes, as its species produce zygospore in the sexual reproductive phase.They are also called bread, black or pin mould.These can reproduce by vegetative, asexual and sexual methods through fragmentation, sporangiospores and zygospores formation, respectively. In fact, it is a heterothalic organism, which for its sexual reproduction requires the mating of two thalli of different charges to create a sexed spore. Zygomycetes have a thallus of coenocytic hyphae in which the nuclei are haploid when the organism is in the vegetative stage. Asexual Reproduction: It takes place by the formation of sporangiospore and chlamydospore. The life cycle of Rhizopus is given in figure 1.27. Sporulation ­ is the process of making spores. The septate ascogonium, ascogenous hyphae fusion or diploid nucleus (synkaryon) is the young ascus. During plasmogamy, a zygosporangium forms, containing multiple haploid nuclei from the two parents. Third hypha is asexual. Rhizopus, cosmopolitan genus of some 10 species of filamentous fungi in the family Rhizopodaceae (formerly Mucoraceae), in the order Mucorales.

Aims: The life cycle of the dimorphic fungus Mucor circinelloides was studied in a temperature-controlled flow-through cell, which constitutes an ideal tool when following the development of individual cells, with a view to understanding the growth and differentiation processes occurring in and between the different morphological forms of the organism. They are found in a wide variety of organic substances , including "mature fruits and vegetables", jellies, syrups, leather, bread, peanuts, and tobacco. Rhizopus is a member of the Zygomycota. $144. These are called sporangiophores. There are four types of life cycle in algae such as; 1. Sexual reproduction.
