Coenocytic mycelium is found in :-

Options

A. Rhizopus
B. Mucor
C. Penicilium
D. Both 1 and 2

Answer

### Step-by-Step Solution:

1. **Understanding Coenocytic Mycelium**:
- Coenocytic mycelium refers to a type of fungal mycelium that is multinucleated and lacks septa (cross walls). This means that the hyphae (the filamentous structures of fungi) are continuous and have multiple nuclei within a single cell-like structure.

2. **Identifying Characteristics**:
- Since coenocytic mycelium is characterized by the absence of septa, it is also referred to as aseptate hyphae. This is an important distinction because it helps in identifying the type of fungi that possess this structure.

3. **Classifying Fungi**:
- Fungi are classified into different groups. The main groups mentioned are:
- Phycomycetes (lower fungi)
- Ascomycetes (higher fungi)
- Basidiomycetes (higher fungi)
- Deuteromycetes (higher fungi)

4. **Determining the Group with Coenocytic Mycelium**:
- Among these groups, phycomycetes are known to have coenocytic mycelium. This group includes fungi like Rhizopus and Mucor, which are characterized by their aseptate hyphae.

5. **Conclusion**:
- Therefore, the correct answer to the question "Coenocytic mycelium is found in:" is **Phycomycetes**.

### Final Answer:
Coenocytic mycelium is found in **Phycomycetes**.
