In centriole each peripheral fibril is a_____.

Answer

To answer the question "In centriole each peripheral fibril is a_____", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Centrioles**:
- Centrioles are cylindrical structures found in the centrosome of cells. They typically exist in pairs and are oriented perpendicular to each other.

2. **Understand the Composition of Centrioles**:
- Each centriole is composed of nine peripheral fibrils. These fibrils are arranged in a specific manner around the centriole.

3. **Define Peripheral Fibrils**:
- The peripheral fibrils in the centriole are not just simple structures; they are organized into triplets. Each peripheral fibril consists of three microtubules.

4. **Conclusion**:
- Therefore, each peripheral fibril in a centriole is a "triplet".

### Final Answer:
In centriole, each peripheral fibril is a **triplet**.
