The identifying characteristics of the Zygomycota are the formation of a zygospore during sexual reproduction and the lack of hyphal cell walls except in reproductive structures. Many (~100 species) are known plant root symbionts. Structure The mycelia of Zygomycota are divided into three types of hyphae. The rhizoids reach below the surface and function in food absorbtion. Above the surface, sporangiophores bear the spore- producing sporangia. Groups of rhizoids and sporangiophores are connected above the surface by stolons. Cell walls separating individual cells are absent in all but reproductive structures, allowing cytoplasm and even nuclei to move between cells. Figure %: Structure of the Zygomycota Reproduction Like all fungi, Basidiomycota can undergo both asexual and sexual reproduction. Asexual reproduction in Zygomycota is similar to that in other types of fungi, while sexual reproduction...
