Septate and branched mycelium is foundin:-

Options

A. Basidiomycetes
B. Deuteromycetes
C. Ascomycetes
D. All of the above

Answer

To answer the question "Septate and branched mycelium is found in:", we will analyze the options provided and determine which classes of fungi exhibit this characteristic.

### Step-by-Step Solution:

1. **Understand Mycelium Structure**: Mycelium is the vegetative part of fungi, consisting of a network of fine white filaments called hyphae. The mycelium can be classified based on its structure.

2. **Define Septate Mycelium**: Septate mycelium refers to hyphae that are divided into compartments by septa (cross-walls). This is a characteristic feature of many fungi.

3. **Identify the Fungal Classes**:
- **Basidiomycetes**: This class includes mushrooms and shelf fungi. They typically have septate and branched mycelium.
- **Deuteromycetes**: Also known as imperfect fungi, this group includes fungi that do not have a known sexual reproduction stage. They also exhibit septate and branched mycelium.
- **Ascomycetes**: This class includes yeasts and molds. Ascomycetes also have septate and branched mycelium.

4. **Evaluate the Options**:
- The options provided are:
- a) Basidiomycetes
- b) Deuteromycetes
- c) Ascomycetes
- d) All of the above

5. **Conclusion**: Since all three classes (Basidiomycetes, Deuteromycetes, and Ascomycetes) exhibit septate and branched mycelium, the correct answer is **d) All of the above**.

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