Question
Why does bread mould grow profusely on a moist slice of bread rather than on a dry slice of bread?
Advertisements
Solution
Bread mould reproduces asexually through production of thick-walled spores. These spores require moisture to germinate to form hyphae and nutrients to grow profusely. Both conditions (moisture and nutrients) required for profuse growth of bread mould are provided on moist slice of bread whereas dry slice of bread provides only nutrients not the moisture.
