Bread mould, SEM

Bread mould. Coloured scanning electron micrograph (SEM) of a sporangium of a bread mould (Rhizopus stolonifer). Spores develop in these sac-like bodies, or sporangia (globular structure). The mould spores then circulate freely in the air, which germinate a network of hyphae (threads) if they land on a favourable medium. Their function is to absorb food for growth and for spore production. Rhizopus sp. produces stolons, or aerial hyphae, which on contact with the medium grow rhizoids (rootlets). These anchor the mould and absorb water. Magnification: x700 at 10x8 inch size
