What is Somatogamy in fungi?

somatogamy (noun,no plural) – the fusion of two somatic hyphae acting as gametes for two sexually compatible mycelia. This is the most reduced form of sexual reproduction. It is very common, if indeed typical for basidiomycetes, but not prevalent in ascomycetes.

What is vegetative propagation with diagram? A new plant can be developed using the method of vegetative propagation. Vegetative propagation can take place from the stem in ginger and potatoes.

What is the difference between vegetative part and reproductive part? The vegetative parts includes the roots, stems,leaves and the reproductive parts include flowers. … The vegetative parts can reproduce new plants by the process of vegetative propagation but the reproductive parts cannot produce new plants directly instead they produce precursor of new plants that are seeds or fruits.
