Coenocytic, aseptate hyphae are a characteristic feature of

Options

A. Penicillium
B. Agaricus
C. Yeast
D. Rhizopus

Answer

To solve the question regarding coenocytic, aseptate hyphae, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Coenocytic Hyphae**: These are hyphae that do not have septa (cross-walls) separating the cells, resulting in a continuous cytoplasmic mass with multiple nuclei.
- **Aseptate Hyphae**: This term is synonymous with coenocytic hyphae, indicating the absence of septa.

2. **Identify the Options**:
- Option A: Penicillium
- Option B: Agaricus
- Option C: Yeast
- Option D: Rhizopus

3. **Analyze Each Option**:
- **Penicillium**: This genus typically has septate hyphae and is known for producing antibiotics.
- **Agaricus**: This is a genus of mushrooms (e.g., Agaricus bisporus) that also has septate hyphae.
- **Yeast**: Yeasts are unicellular fungi and do not have hyphae in the traditional sense, thus they do not exhibit coenocytic or aseptate characteristics.
- **Rhizopus**: This genus is known for having coenocytic, aseptate hyphae. It is a common saprophytic fungus found on decaying organic matter and can also act as a parasite.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option D: Rhizopus**, as it is the only one among the options that possesses coenocytic, aseptate hyphae.

### Final Answer:
The correct answer is **Option D: Rhizopus**.
