In ascomycetes and basidomycetes, the dikaryotic cell is:-

Options

A. Haploid
B. Diploid
C. Triploid
D. Polyploid

Answer

To solve the question regarding the nature of the dikaryotic cell in ascomycetes and basidiomycetes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Dikaryotic Cell**: A cell that contains two genetically distinct nuclei.
- **Ascomycetes and Basidiomycetes**: Two major groups of fungi.

2. **Process of Plasmogamy**:
- In fungi, the process of plasmogamy refers to the fusion of the cytoplasm of two parent cells (hyphae) without the fusion of their nuclei.

3. **Formation of Dikaryotic Hyphae**:
- After plasmogamy, the resulting structure is a dikaryotic hypha, where each cell contains two haploid nuclei (one from each parent).

4. **Nuclear Fusion**:
- Eventually, these two haploid nuclei may fuse to form a diploid nucleus, but this occurs after the dikaryotic stage.

5. **Conclusion on Dikaryotic Cell Nature**:
- Since the dikaryotic cell contains two haploid nuclei, it is classified as haploid in nature, despite having two nuclei.

6. **Answer the Question**:
- Therefore, the correct answer is that in ascomycetes and basidiomycetes, the dikaryotic cell is **haploid**.

### Final Answer:
The dikaryotic cell in ascomycetes and basidiomycetes is **haploid**.
