How bread mould moves?

Bread mold, primarily caused by fungi like Rhizopus stolonifer, spreads through the release of spores into the air. These spores land on suitable surfaces, such as bread, and germinate when conditions are favorable—typically warmth and moisture. The mold then grows through the bread by extending its hyphae, which absorb nutrients and allow the fungus to proliferate. This process results in the visible growth of mold and the eventual decay of the bread.
