Answer:
Centriole- The centrosome is made up of 2 centrioles which are right angled to each other and is composed of a protein known as tubulin.It produces spindle apparatus at the time of cell division.Each centriole has 9 peripheral groups of microtubules (triplet) with no central microtubules thus, this type of arrangement in centriole is called 9+0 pattern.
So, the correct answer is 'Centriole'.
Explanation:
Tubulin is a dimer protein. They arrange spirally and grow into one strand known as microtubule. Such 9 in periphery and 2 central double axis makes a 9+2 arrangement of cilia and flagella. When it starts, the basal body, which is attached to the cell membrane has 9+0 arrangements.
