Answer: They are multicellular in nature and some rhizopus causes fungal infection and they cause fatal disease. They grow in filamentous, branching hyphae that generally lack cross-walls, i.e, they are coenocytic. They reproduce by spore formation both by asexual and sexual mode of reproduction as sporangiospores are produced inside a spherical structure, the sporangium. Sporangia are supported by a large apophysis atop a long stalk, the sporangiophore. In sexual reproduction, a dark zygospore is produced at the point where two compatible mycelia fuse. After germination, zygospores produced colonies that are genetically different from their parents.
