The given diagram shows the secondary mycelium of a basidiomycete.
Correct answer: C. Plasmogamy occurs between positive and negative mating types
- A. Meiosis occurs in the gills of basidiocarp
- B. Germination of basidiospores takes place in the basidiocarp
- C. Plasmogamy occurs between positive and negative mating types
- D. Karyogamy in the basidia leads to the formation of diploid nuclei
Explanation
Plasmogamy is the fusion of the cytoplasm between two compatible primary, haploid mycelia (often designated as positive and negative mating types). This process brings the two haploid nuclei into the same cell, initiating the dikaryotic (N+N) secondary mycelium shown in the diagram.
