Which cellular structure organisation is like the cartwheel?

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which cellular structure organization resembles a cartwheel.

2. **Understanding Centrosome**: The centrosome is a cell organelle that plays a crucial role in cell division and organization of microtubules.

3. **Structure of Centrosome**: The centrosome consists of two cylindrical structures known as centrioles.

4. **Arrangement of Centrioles**: The centrioles are arranged perpendicularly to each other within the centrosome.

5. **Pericentriolar Material**: Surrounding the centrioles is a substance known as amorphous pericentriolar material, which contributes to the overall structure.

6. **Cartwheel Analogy**: The perpendicular arrangement of the centrioles and the surrounding material gives the centrosome a resemblance to a cartwheel, hence the analogy.

7. **Conclusion**: Therefore, the cellular structure organization that is like a cartwheel is the centrosome.
