Question

Given is the representation of life cycle of members of classes Ascomycetes and Basidiomycetes. Select the correct option for processes A, B and C.

• A. A - Karyogamy, B - Plasmogamy, C - Meiosis
• B. A - Plasmogamy, B - Karyogamy, C - Meiosis
• C. A - Plasmogamy, B - Meiosis, C - Karyogamy
• D. A - Karyogamy, B - Meiosis, C - Plasmogamy

Answer 1

Answer: (B)

A - Plasmogamy, B - Karyogamy, C - Meiosis

In fungi, karyogamy is delayed and occurs just before meiosis. In the stage intervening between plasmogamy and karyogamy, the cells often contain two nuclei or dikaryons.

So, the correct option is 'A - Plasmogamy, B - Karyogamy, C - Meiosis'.
