1. Centrioles and centrosomes play significant role in formation of spindle apparatus during cell division. 

2. Centrosome is usually found near the nucleus of an animal cell. 

3. It contains a pair of cylindrical structures called centrioles. 

4. The cylinder (centriole) are perpendicular to each other and are surrounded by amorphous substance called pericentriolar material.

5. Each cylinder of centriole is made up of nine sets of triplet microtubules made up of tubulin. 

6. Evenly spaced triplets are connected to each other by means of non-tubulin proteins. 

7. At the proximal end of centriole, there is a set of tubules called hub. 

8. The peripheral triplets are connected to hub by means of radial spokes. Due to this proximal end of centriole looks like a cartwheel.

9. Centriole forms basal body of cilia and flagella.
