The zygote of Rhizopus results from the union of two haploid hyphae. The mature zygote is multinucleated, and it undergoes meiosis to form four haploid nuclei. These nuclei then migrate to the periphery of the zygote and become surrounded by cell walls, forming four new haploid hyphae.
The structures found on either side of the zygote Rhizopus are called rhizoids. Rhizoids are hyphae that grow from the zygote and help to anchor it to the substrate. Rhizoids also absorb nutrients from the substrate and transport them to the zygote.
