Cellulosic cell wall, coenocytic mycelium, aquatic habitat are present in the members of fungi of class :

Options

A. Oomycetes
B. Zygomycetes
C. Ascomycetes
D. Basidiomycetes

Answer

To solve the question regarding which class of fungi exhibits a cellulosic cell wall, coenocytic mycelium, and an aquatic habitat, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics**: The question mentions three specific characteristics:
- Cellulosic cell wall
- Coenocytic mycelium
- Aquatic habitat

2. **Understand the Classes of Fungi**: The options provided are:
- Homocytes
- Zygomycetes
- Ascomycetes
- Basidiomycetes

3. **Analyze Each Class**:
- **Homocytes (or Oomycetes)**: These fungi-like organisms have a cellulosic cell wall and can be found in aquatic habitats. They often exhibit coenocytic mycelium.
- **Zygomycetes**: These fungi typically have a chitinous cell wall and do not possess coenocytic mycelium. They are usually terrestrial.
- **Ascomycetes**: Known for their sac-like structures (asci) for spore production, they do not have a cellulosic cell wall and are primarily terrestrial.
- **Basidiomycetes**: These include mushrooms and have a chitinous cell wall, not cellulosic, and are also primarily terrestrial.

4. **Conclusion**: Based on the analysis, the class that matches all three characteristics (cellulosic cell wall, coenocytic mycelium, and aquatic habitat) is **Homocytes** (or Oomycetes).

5. **Final Answer**: The correct option is **Homocytes**.
