Question

Why does the bread mold grow profusely on a moist slice of bread rather than on a dry slice of bread?

Answer 1

Bread mold:

1. Rhizopus (bread mold) is a multi-cellular organism that bears thread-like filamentous structures called hyphae.
2. The hyphae bear a reproductive structure known as sporangia. The sporangia consist of numerous small cells called spores which are capable of forming new Rhizopus.
3. Fungus such as bread mold requires nutrition, optimum temperature, and moisture to reproduce asexually.
4. When the slice of bread is moist the bread mold gets both nutrients and moisture. Thus, optimum growth of the hyphae takes place.
5. But in the case of the dry slice of bread, it provides nutrients but due to lack of moisture, the bread mold cannot grow.
