When a moist slice of bread was kept aside for a few days then some organism grew on it to form a white cottony mass which later turned black. When this slice of bread was observed through a magnifying glass, then fine thread-like projections and thin stems having bulb-like structures at the top were seen.
(a) What is the common name and scientific name of the organism which grew on the moist slice of bread ?
(b) How did this organism grow on the moist slice of bread automatically?
(c) What are the fine, thread-like projections on the surface of slice of bread known as ?
