Mycelium is septate and branched in

Options

A. 1)Ascomycetes
B. 2)Basidiomycetes
C. 3)Deuteromycetes
D. 4)All the above

Answer

To determine in which group of fungi the mycelium is septate and branched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Mycelium**:
- Mycelium is the vegetative part of fungi, composed of a network of thread-like structures called hyphae.
- The mycelium can be classified based on its structure, which can be septate (having cross-walls) or coenocytic (without cross-walls).

2. **Analyzing the Options**:
- **Option 1: Ascomycetes (Sac Fungi)**:
- Ascomycetes are known to have septate and branched mycelium. Therefore, this option is correct.

- **Option 2: Basidiomycetes (Club Fungi)**:
- Basidiomycetes also possess mycelium that is septate and branched. Thus, this option is also correct.

- **Option 3: Deuteromycetes (Imperfect Fungi)**:
- Deuteromycetes, which are often classified based on their asexual reproduction, also have mycelium that is septate and branched. Hence, this option is correct as well.

3. **Conclusion**:
- Since all three groups (Ascomycetes, Basidiomycetes, and Deuteromycetes) have mycelium that is both septate and branched, the correct answer is:
- **Option 4: All of the above**.

### Final Answer:
The mycelium is septate and branched in **all of the above** (Ascomycetes, Basidiomycetes, and Deuteromycetes).
