Question

Select the odd one out w.r.t. basidiomycetes.

• A. Sex organs are absent
• B. Karyogamy and meiosis takes place in basidium
• C. Fruiting body is called basidiocarp
• D. Basidiospores are endogenously produced on basidium

Answer 1

Answer: (D)

Basidiospores are endogenously produced on basidium

Basidiomycetes are the most advanced fungi. The basidiocarp or the fruiting body is a large sporophore in which sexually produced spores are formed on a club-shaped basidium. Karyogamy and meiosis occur in the club-shaped basidium. A basidium produces four exogenous meiospores or basidiospores.

Thus, from the above discussion, it is clear that basidiospores are exogenously formed.

So, the correct answer for the odd statement is 'Basidiospores are endogenously produced on basidium'.
