Question

What is plasmogamy and karyogamy? How the plasmogamy differ from karyogamy?​

Answer 1

Answer:

Plasmogamy in lower fungi occurs through the union of the two cytoplasms of fungal gametes. But in higher fungi, the two opposite mating types of the fungal thalli are also capable of fusing together, forming the diksryotic cell stages. Plasmogamy is immediately followed by karyogamy in lower fungi. In higher fungi, karyogamy is delayed for several generations, maintaining the dikaryotic stage of cells. The main difference between plasmogamy and karyogamy is that plasmogamy is the fusion of two hyphal protoplasts while karyogamy is the fusion of two haploid nuclei in fungi.
