Reproduction is in two modes; sexual reproduction and asexual reproduction Most of the fungi show asexual reproduction while some use sexual reproduction. Asexual reproduction is accomplished by the production of spores. Asexual spores are produced in the structures called sporangia. Hence, sporangia are asexual reproductive bodies. Sexual reproduction is accomplished by the production of sexual cells called gametes Gametes are haploid, and the fusion of two male and female gametes produces a diploid zygotewhich then develops into a new organism. Gametes are produced in the structures called gametangia. The key difference between sporangia and gametangia is that sporangia are the asexual structures that produce asexual spores while gametangia are the sexual structures that produce sexual spores or the gametes.
