In Basidiomycetes: 1.The asexual spores are generally not found 2. Vegetative reproduction by fragmentation is common. 3. The *** organs are present 4. plasmogamy is brought about by fusion of two vegetative or somatic cells of same strain or genotype. 5. The resultant structure of plasmogamy is dikaryotic which ultimately gives rise to basidium. 6.Karyogamy and meiosis take place in the basidium producing four basidiospores. The basidiospores are exogenously produced on the basidium . 7. The basidia are arranged in fruiting bodies called basidiocarps.

1 Answer

(C) is the right answer.

Basidiomycetes - The asexual spores are generally not found, but vegetative reproduction by fragmentation is common. The *** organs are absent, but plasmogamy is brought about by fusion of two vegetative or somatic cells of different strains or genotypes. The resultant structure is dikaryotic which ultimately gives rise to basidium. Karyogamy and meiosis take place in the basidium producing four basidiospores. The basidiospores are exogenously produced on the basidium (pl.: basidia). The basidia are arranged in fruiting bodies called basidiocarps.
