Question

In Basidiomycotina, well-developed sex organs are present.
A. True
B. False

Answer 1

Hint: Basidiomycotina are the most advanced category of all fungal groups. Includes both saprophytic and parasite types (Mushrooms, Puffballs, Rusts, etc.). Basidiomycotina is a filamentous fungus composed of hyphae.

Complete answer:
In basidiomycetes, sexual organs are absent since somatogamy is a secular reproduction. In somatogamy, plasmogamy is created by the fusion of two vegetative cells. There is therefore no need for sex organs. The development of sex organs is absent throughout the basidiomycotina community. As with all fungi, Basidiomycota may experience sexual and sexual reproduction. Basidiomycota reproduces asexually by budding or asexual spore formation. Budding develops when the outgrowth of the parent cell is divided into a new cell. Any cell in the body will bud. Formation of asexual spore. Then the cell walls thicken into a protective coat. The protected spores are broken off and disbursed. Sexual reproduction in Basidiomycota occurs in the fruiting body, in specialized cells called basidia. The basidia itself is developed by plasmogamy between two different spores of mycelia. Plasmogamy results in binucleate hyphae, i.e. hyphae with two types of nucleus, one from each parent. The diploid stage is a really quick one. Soon after fusion, meiosis occurs, consisting of four haploid nuclei. The nucleus then moves to the basement terminus and forms four primary projections. These projections are divided into spores by cell walls.
So, the correct solution is (B).

Note: Basidiomycota appears to have mutually distinct, compatible haploids that are typically mycelia, composed of filamentous hyphae. Higher Basidiomycota is likely to cause severe diseases of forest and shade trees and in destroying timber, railroad ties, etc. In tropical areas where atmospheric humidity is high, it is just not rare to see old automobiles with viable fungi growing from car remnants.
