False colour scanning electron micrograph of rhizoids,or "rootlets" of the bread mould,Rhizopus stolonifer,on the surface of bread. Spores circulate freely in the air. When they alight on a favourable medium,they germinate a network of hyphae (threads),whose function it is to absorb food for growth & spore production. Rhizopus produces stolons,or aerial hyphae,which on contact with a medium grow rhizoids. These anchor the fungus & absorb some water. Specialised hyphae called sporangiophores (seen here) grow opposite the rhizoids & bear spore containing sacs or sporangia at the tips. Magnification: X 170 at 35mm size.
