Large time gap exists between plasmogany and Karyogamy in

Options

A. Ascomycates
B. Basidiomycetes
C. Zygomycetes
D. 1 and 2

Answer

To answer the question regarding the large time gap that exists between plasmogamy and karyogamy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Plasmogamy**: This is the fusion of the cytoplasm of two parent cells in fungi.
- **Karyogamy**: This is the fusion of the nuclei of the two parent cells after plasmogamy.

2. **Identify the Process**:
- The process that includes both plasmogamy and karyogamy is known as **syngamy**, which is a form of sexual reproduction in fungi.

3. **Recognize the Types of Fungi**:
- The question provides four options: Ascomycetes, Basidiomycetes, Zygomycetes, and a combined option of Ascomycetes and Basidiomycetes.

4. **Analyze the Options**:
- Ascomycetes and Basidiomycetes are known to have a significant time gap between plasmogamy and karyogamy. This is due to the formation of a dikaryotic stage, where the two nuclei coexist in the same cell without fusing immediately.

5. **Conclusion**:
- Since both Ascomycetes and Basidiomycetes exhibit this large time gap due to their dikaryotic phase, the correct answer is **Option D** (which indicates both Ascomycetes and Basidiomycetes).

### Final Answer:
The correct answer is **Option D: Ascomycetes and Basidiomycetes**.
