Q1
There is a myth that immediately after heavy rains in forest, mushrooms appear in large number and make a very large ring or circle, which may be several metres in diameter. These are called as ‘fairy rings’. Can you explain this myth of fairy rings in biological terms?
Q2
Neurospora an ascomycetes fungus has been used as a biological tool to understand the mechanism of plant genetics much in the same way as Drosophila has been used to study animal genetics. What makes Neurospora so important as a genetic tool?
Q3
Cyanobacteria and heterotrophic bacteria have been clubbed together in eubacteria of kingdom–Monera as per the ‘five kingdom classification’ even though the two are vastly different from each other. Is this grouping of the two types of taxa in the same kingdom justified? If so, why?
Discuss the cellular composition of cyanobacteria and heterotrophic bacteria that make them introduced in eubacteria.

Neurospora fungus was selected to be a very good tool in genetics because this fungus can be grown easily under laboratory conditions by providing ‘minimal medium’ like inorganic salts, carbohydrates source and vitamin (biotin). 
Also under X-ray treatment the mutations can be easily introduced in the fungal cells and meiotic division can be easily seen.
