Caption

False colour scanning electron micrograph of tightly packed spores in a fragmenting sporangium of the bread mould, Rhizopus stolonifer. Spores circulate freely in the air. When they alight on a favourable medium, they germinate a network of hyphae (threads). Their function is to absorb food for growth & for spore production. Rhizopus produces stolons, or aerial hyphae, which on contact with a medium grow rhizoids or "rootlets". They anchor the fungus & absorb some water. Spores develop in saclike bodies, or sporangia. The wall fragments (white bits) under pressure from the maturing spores, releasing them for dispersal. Magnification: X 570 at 35mm size. Original is bw print b250/356.
