The male (+) and female (-) gametangia fuse in Rhizopus, and the gametangial copulation leads to the formation of a zygospore, which contains many pairs of nuclei. These pairs of nuclei fuse to produce diploid nuclei, while others degenerate. On germination, the inner layer comes out after cracking the outer walls and produces a promycelium.

Which is unicellular fungus?
1 Yeast
2 E. coil
3 Nostoc
4 Albugo
Explanation:
Yeast belongs to class Ascomycetes. It is a colourless, unicellular, non-mycelial plant. It is also called as "Sugar fungus" because it converts sugars and starches into alcohol and carbon dioxide during the fermentation process.

Slimy mass of protoplasm with many nuclei and an amoeba-like thalloid body is a characteristic feature of
1 Ascomycetes
2 Actinomycetes
3 Phycomycetes
4 Basidiomycetes
5 Myxomycetes
Explanation:
E Myxomycetes (slime mould) are multinucleated. amoeboidal \& diploid. They are found in decaying leaves, in soil, and dark \& cool conditions. They are saprophytic and lack chlorophyll. The plasmodial stage resembles protozoa, and fruiting bodies from spores resembling fungi.

Fungi can be stained with :
1 Fast green
2 Cotton blue
3 Grams stain
4 PAS
Explanation:
Fungi can be stained with cotton blue, which provide blue colour of chitinous cell wall. - Fast green is used as a quantitative stain for histones at alkaline $\mathrm{pH}$ after acid extraction at DNA. It is also used as a protein stain in electrophoresis. - Gram stain is a staining method used to classify bacteria into Gram positive \& Gram negative. - Periodic-acid schiff (PAS) is a staining method used to detect polysaccharides such as glycogen and mucosubstance.

When a fungus completes its life cycle on two hosts, it is called
1 heterothallic
2 monothallic
3 heteroecious
4 autoecious.
Explanation:
When a fungus completes its life cycle on two hosts, it is called heteroecious. It requires two unrelated hosts to complete their life cycle. The primary host is the host in which the parasites spends its adult life. Example : Puccinia graminis : the primary host is barley and barberry is the alternate host.
