False-colour scanning electron micrograph of a bread mould,Mucor mucedo,growing on the surface of a slice of bread. Spores circulate freely in the air. When they alight on a favourable medium,they germinate an extensive network of thread-like hyphae,the function of which is to absorb nourishment for growth & for the production of sporangia,which contain a new crop of spores. The picture shows the hyphae covering the surface of the bread. The globular structures at the ends of specialised hyphae (sporangiophores) are the sporangia,where the spores mature until the wall ruptures & dispersal occurs. Magnification: x30 at 35mm size,x50 at 6x4.5cm size. BW is print B250/328 | |
