False col SEM of rhizoids

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
