Expert Answer
(a) Spores of mould were present in air. Therefore, they were present in the bell jar.
(b) If moist bread was placed in the refrigerator, mould spores would not have germinated. This is because spores need moist and warm conditions to germinate.
(c) On moist bread, the spores germinate first to form the mycelium.
