Question:

Dikaryophase of fungus is-

Options:

1. Two nuclei per cell
2. Diploid nucleus
3. Two nuclei per mycelium
4. More than one options are correct.

Solution:

Page 23, XI NCERT. The dikaryophase of fungus is "two nuclei per cell." The term "dikaryon" refers to a cell or hyphae that contains two genetically distinct haploid nuclei that are not fused. This condition is common in many fungi, particularly in the Basidiomycetes and some Ascomycetes. The nuclei in a dikaryon are kept separate by a specialized compartment called the clamp connection, which ensures that each new cell receives one nucleus from each parent cell during cell division. The dikaryophase is an important stage in the sexual reproduction of many fungi, as it allows for genetic recombination and the formation of a diploid nucleus, which can then undergo meiosis to produce haploid spores.
