By unraveling the What role do the spores play in the life cycle of rhizopus? Rhizopus stolonifer, a species of bread mold, produces sporangia that bear sporangiospores (asexual spores). Among plants—all of which have a life cycle characterized by alternating generations of asexually and sexually reproducing individuals—spores are the reproductive agents of the asexual generation. The life cycle of Zygomycota encompasses both sexual and asexual reproduction, alternating between non-motile sporangiospores, coenocytic hyphae, and the formation of a zygosporangium within which a zygospore develops. The fungi usually reproduce asexually by producing sporangiospores (Figure 1). • Then the Sporangium separates into two regions Fungi-Chapter 31 Refer to the images of life cycles of Rhizopus, Morchella and Mushroom in your text book and lab manual. Mucor reproduces asexually through the formation of sporangiospores within the sporangium.
