In which group of fungi, spores are flagellated?

Options

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

Answer

To answer the question "In which group of fungi are spores flagellated?", we can follow these steps:

### Step 1: Identify the Groups of Fungi
We need to look at the different groups of fungi mentioned in the question. The groups we will consider are:
1. Ascomycetes
2. Zygomycetes
3. Phycomycetes
4. Basidiomycetes

### Step 2: Analyze Each Group
Next, we will analyze each group to determine whether they produce flagellated spores.

- **Ascomycetes**: This group produces spores known as ascospores, which are not flagellated. They are formed in a sac-like structure called an ascus.

- **Zygomycetes**: This group produces non-motile spores. They do not have flagella and are typically formed in a structure called a zygosporangium.

- **Phycomycetes**: This group is known for being aquatic fungi, and they produce flagellated spores. These spores are motile and can swim in water due to the presence of flagella.

- **Basidiomycetes**: This group produces basidiospores, which are not flagellated. They are formed on a structure called a basidium.

### Step 3: Conclusion
From the analysis, we can conclude that the only group of fungi that produces flagellated spores is **Phycomycetes**.

### Final Answer
The answer to the question is **Phycomycetes**.
