Pattern of organisation in centrioles is
(a) 9+2
(b) 9+3
(c) 9+0
(d) 9+1

Options

A. 9+2
B. 9+3
C. 9+0
D. 9+1

Answer

To solve the question regarding the pattern of organization in centrioles, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Centrioles**:
- Centrioles are cylindrical structures found in the cells of most eukaryotes. They play a crucial role in cell division and are part of the centrosome.

2. **Structure of Centrioles**:
- Each centriole is composed of microtubules, which are protein structures made of tubulin.

3. **Arrangement of Microtubules**:
- The microtubules in a centriole are arranged in a specific pattern. Each centriole typically has nine groups of microtubule triplets arranged in a circular formation.

4. **Identifying the Pattern**:
- The arrangement in centrioles is referred to as "9+0", meaning there are 9 peripheral microtubule triplets and no central microtubules.

5. **Conclusion**:
- Based on the structural organization of centrioles, the correct answer to the question is (c) 9+0.

### Final Answer:
The pattern of organization in centrioles is (c) 9+0.
