Question

Quizplus · Accepted Answer

When black bread mold reproduces sexually the ends (+ and -) of hyphae join and the haploid nuclei fuse forming a thick walled zygospore. After a period of dormancy the zygospore undergoes meiosis and then germination. Sporangia form at the tips of aerial hyphae and produce spores. These spores give rise to new mycelia. In asexual reproduction sporangia are produced on the ends of some of the hyphae.Bloom's
