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

EDITORS COMMENTS
This print showcases the intricate world of bread mould, revealing its vibrant colors and fascinating structure. In this coloured scanning electron micrograph (SEM), we are presented with a close-up view of a sporangium belonging to the bread mould species Rhizopus stolonifer. Sporangia, which resemble sac-like bodies in this image, play a crucial role in the reproductive cycle of bread mould. Within these globular structures, spores develop and eventually become airborne. Once released into the environment, these tiny mould spores have the potential to germinate if they land on a suitable medium. The network of hyphae seen here is responsible for absorbing nutrients necessary for growth and spore production. Interestingly, Rhizopus stolonifer produces aerial hyphae called stolons that grow rhizoids upon contact with a favorable medium. These rootlets serve as anchors for the mould while also absorbing water. At an impressive magnification level of x700 at 10x8 inches in size, this SEM image allows us to appreciate both the beauty and complexity found within nature's microscopic realm. Whether you're captivated by fungi or simply intrigued by scientific imagery, this photograph offers an awe-inspiring glimpse into the hidden world of bread mould and its remarkable life cycle.
