Fruiting body in mushrooms is

Options

A. Haploid and dikaryotic, and parasite
B. Diploid and dikaryotic and saprophytic
C. Haploid dikaryotic, and saprophytic
D. Diploid, monokaryotic, saprophytic

Answer

To answer the question "Fruiting body in mushrooms is," we need to analyze the options provided and understand the characteristics of mushrooms, particularly their fruiting bodies.

### Step-by-Step Solution:

1. **Understanding Fruiting Bodies**:
- The fruiting body of mushrooms is the reproductive structure that produces spores. It is crucial to know the ploidy level (haploid or diploid) and the type of nuclei present (monokaryotic or dikaryotic).

2. **Identifying Ploidy**:
- In fungi, the fruiting body is primarily haploid. This means it contains one set of chromosomes.

3. **Understanding Dikaryotic Condition**:
- In many fungi, including mushrooms, after sexual reproduction, the hyphae can become dikaryotic. This means that each cell contains two nuclei (one from each parent). This is a unique feature of certain fungi, including the fruiting bodies of mushrooms.

4. **Determining the Nutritional Mode**:
- Mushrooms are generally saprophytic, meaning they obtain nutrients from dead and decaying organic matter. They are not parasitic, as they do not derive nutrients from living hosts.

5. **Evaluating the Options**:
- Now, let's evaluate the options given:
- **Option 1**: Haploid and dikaryotic and parasitic - Incorrect (it is not parasitic).
- **Option 2**: Diploid and dikaryotic and saprophytic - Incorrect (the fruiting body is not diploid).
- **Option 3**: Haploid, dikaryotic, and saprophytic - Correct (this matches our findings).
- **Option 4**: Diploid, monokaryotic, and saprophytic - Incorrect (the fruiting body is not diploid or monokaryotic).

6. **Conclusion**:
- The correct answer is **haploid, dikaryotic, and saprophytic**.

### Final Answer:
The fruiting body in mushrooms is **haploid, dikaryotic, and saprophytic**.
