Question

Explain the sexual cycle in Fungi.

Answer 1

Answer:

Hi friends,

The sexual cycle of the kingdom fungi involves the three phases:

1)Plasmogamy:

It is the process of the fusion of the cytoplasm. It involves the fusion of the protoplasts of the gametes or the sex cells which are compatible in nature. Thus, because of this, the two compatible nuclei come close to each other.

2)Karyogamy:

It is the process of the fusion of the nucleus. It leads to the formation of the diploid nucleus. The structure is called dikaryon which divides mitotically along with the division of the cytoplasm. Later on, the two nuclei of the dikaryon fuse to form a diploid zygote.

3)Meiosis:

It is the reductional type of the cell division. The zygote formed in the karyogamy phase goes reductional division or meiosis and thus forming haploid meiospores.

Answer 2

Answer:

Sexual reproduction in the fungi consists of three sequential stages: plasmogamy, karyogamy, and meiosis. The diploid chromosomes are pulled apart into two daughter cells, each containing a single set of chromosomes (a haploid state). ... In most fungi the zygote is the only cell in the entire life cycle that is diploid.
