Bread mould sporangium. Scanning electron micrograph (SEM) of a young fruiting body (sporangium) of the common bread mould Mucor. The sporangium contains the fungi's reproductive spores which,when released,will circulate freely in the air. When they alight on a favourable medium,the spores germinate to produce a network of hyphae,which function to absorb food for growth and spore production. A sporangium grows at the end of a specialised hypha called a sporangiophore. When the spores are mature,the sporangium's wall disintegrates,releasing the spores.
