Differbetween
The main difference between binucleate and dikaryotic is that binucleate is the containment of two nuclei, whereas dikaryotic is the presence of two genetically distinct nuclei inside the cell. ... Both conditions have two nuclei inside a cell.

What does Dikaryotic mean?
Medical Definition of dikaryotic
: characterized by the presence of two nuclei in each cell.
What's the difference between Dikaryotic and Heterokaryotic?
dikaryotic does - by definition - mean that there are exactly two nuclei in the cells, it does not say that the two nuclei are genetically distinct! heterokaryotic does also mean only one thing: the nuclei (the number is not important) are genetically distinct.
What is Dikaryon and Dikaryophase?
In the stage intervening between plasmogamy and karyogamy the cells often contain two nuclei or Dikaryons (n+n). Such cells are called dikaryotic cells. The phase is known as Dikaryophase which takes place in Ascomycetes and Basidiomycetes.
What is meant by Dikaryotic fungi?
di·kar·y·on
(dī-kăr′ē-ŏn′, -ən) A hypha occurring in certain fungi after sexual reproduction in which each compartment contains two nuclei, one from each parent. [di- + Greek karuon, nut, kernel; see karyo-.]
What is Dikaryotic condition?
Among other things, the unifying synapomorphy for this clade is the dikaryotic condition, a condition in which the cell is neither diploid nor haploid, but maintains the two parental nuclei as separate entities within vegetative cells following fusion of receptive hyphae.
Are all fungi Dikaryotic?
Fungi exist primarily as filamentous dikaryotic organisms.
From these spores, haploid hyphae grow and ramify, and may give rise to asexual sporangia, special hyphae which produce spores without meiosis. ... Some fungi, especially the chytrids and zygomycetes, have a life cycle more like that found in many protists.
What is the Heterokaryotic stage?
Heterokaryotic refers to cells where two or more genetically different nuclei share one common cytoplasm. It is the antonym of homokaryotic. This is the stage after Plasmogamy, the fusion of the cytoplasm, and before Karyogamy, the fusion of the nuclei.
Are all fungi haploid?
In the majority of fungi, all structures are haploid except the zygote. Nuclear fusion takes place at the time of zygote formation, and meiosis follows immediately. ... Fungi usually reproduce both sexually and asexually. The asexual cycle produces mitospores, and the sexual cycle produces meiospores.
How is Dikaryotic different from diploid?
A diploid cell contains a nucleus with two sets of chromosomes. A dikaryotic cell contains two haploid nuclei.
Why Ascomycetes are called sac fungi?
Ascomycetes are called sac fungi because they form a sac like structure called ascus which contains the sexual spores (Ascospores) produced by the fungi.
How is Dikaryon formed?
Complete answer:
A dikaryon is a pair of linked but unfused haploid nuclei of a fungus cell capable of participating until their final fusion as independent individuals in repeated cell division. A dikaryon is formed when two haploid cells do not spontaneously fuse. ... These cells are called dikaryotic cells.
What is Plasmology?
Plasmogamy is a stage in the sexual reproduction of fungi, in which the protoplasm of two parent cells (usually from the mycelia) fuses together without the fusion of nuclei, effectively bringing two haploid nuclei close together in the same cell.
