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. Original is bw print b250/357.
