what is the difference between yeast and filamentous fungi based on reproduction?
Asexual reproduction in zygomycetes takes place by means of spores from multinucleate sporangia; in ascomycetes, it takes place by means of conidia. Asexual reproduction in basidiomycetes is rare. By contrast most of the yeast reproduction is asexual and takes place by cell fission or budding, when a smaller cell forms from a larger one. The word yeast actually signifies only that these fungi are single-celled. Some yeasts have been derived from each of the three phyla of fungi, although ascomycetes are best represented. Sexual reproductive structures distinguish the three phyla of fungi. Thus, yeasts are classified under the Ascomycetes i.e. when ascospores are produced within a naked ascus, the Basidiomycetes i.e. when basidiospores are formed outside a basidium or the Deuteromycetes i.e. when no sexual phase is observed.
