Final answer:
Phylum Zygomycota is a group of fungi that includes bread molds. They have coenocytic hyphae and reproduce through asexual spore production and sexual zygospore formation. Under a microscope, Zygomycota appears as swollen sporangia filled with spores.
Step-by-step explanation:
Phylum Zygomycota is a group of fungi that includes bread molds like Rhizopus stolonifer. These fungi have coenocytic hyphae, which means their hyphae lack cross walls and contain multiple nuclei. They reproduce both asexually through sporangiospores and sexually through the formation of zygosporangia. Under a microscope, the black tips of bread mold reveal swollen sporangia filled with black spores.
