Fungi belonging to the class Oomycetes are often referred as algal fungi due to :

Options

A. presence of coenocytic mycelium
B. presence of cellulosic cell wall
C. absence of fruit body
D. absence of embryonic stage

Answer

To answer the question regarding why fungi belonging to the class Oomycetes are often referred to as algal fungi, we can break down the reasoning step by step:

### Step-by-Step Solution:

1. **Understanding Oomycetes**:
- Oomycetes, also known as "water molds" or "egg fungi," are a class of fungi that share some characteristics with algae.

2. **Cell Wall Composition**:
- The primary reason Oomycetes are referred to as algal fungi is due to their cell wall composition. Unlike most fungi, which have cell walls made of chitin, Oomycetes have cell walls made of cellulose.

3. **Comparison with Algae**:
- Algae also have cell walls made of cellulose. This similarity in cell wall composition is a significant factor that leads to the classification of Oomycetes as algal fungi.

4. **Presence of Sinusitic Mycelium**:
- The statement regarding the presence of sinusitic mycelium is incorrect in the context of Oomycetes. Sinusitic mycelium is characteristic of another class of fungi, Phycomycetes, and does not apply to Oomycetes.

5. **Absence of Fruiting Body and Embryonic Stage**:
- The claims about the absence of fruiting bodies and embryonic stages in Oomycetes are also incorrect. Oomycetes do have fruiting bodies and an embryonic stage.

6. **Conclusion**:
- Therefore, the correct reason for referring to Oomycetes as algal fungi is due to the presence of a cellulosic cell wall, which is similar to that of algae.

### Final Answer:
Fungi belonging to the class Oomycetes are often referred to as algal fungi due to the presence of a cellulosic cell wall, which is similar to the cell wall composition found in algae.
