Question

Select the correct sequence of events with respect to the fungal sexual cycle.

• A. Karyogamy, plasmognmy and meiosis
• B. Meiosis, plasmogamy and karyogamy
• C. Plasmogamy, karyogamy and meiosis
• D. Meiosis, karyogamy and plasmogamy

Answer 1

The correct option is C Plasmogamy, karyogamy and meiosis

The sequences of events occur in a fungal sexual cycle

1. Plasmogamy- In plasmogamy, the cytoplasm of two cells fuses together without the fusion of nuclei. This process helps to bring the haploid nuclei in the same cell.

2. Karyogamy- It is the fusion of the nuclei. Karyogamy results in the formation of a zygote which is diploid.

3. Meiosis- After the formation of zygote, meiosis (reduction division) starts. After meiosis haploid stage of fungi gets established.

Thus the correct sequence of events is plasmogamy, karyogamy, and meiosis.

So, the correct option is 'Plasmogamy, karyogamy and meiosis'.
