Plasmogamy vs. Karyogamy

Plasmogamynoun

(mycology) Stage of sexual reproduction joining the cytoplasm of two parent mycelia without the fusion of nuclei.

Plasmogamy

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. This state is followed by karyogamy, where the two nuclei fuse together and then undergo meiosis to produce spores.

Karyogamynoun

(biology) The fusion of two nuclei within a cell, especially as the second stage of syngamy.

Karyogamy

Karyogamy is the final step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. Before karyogamy, each haploid cell has one complete copy of the organism's genome.
