Why does Mould Grow on Bread?
Mold grows on bread because it needs food in order to reproduce and grow. The bread provides that food. The level of moisture in the bread is the right level for mold to grow. Mold spores float around in the air. Bread left out can be a landing place for mold spores. It takes just one spore to start mold growing.
