Two centriole<\/strong><\/p>\n<p>Centrioles are small, cylindrical organelles found in animal cells. They are located near the nucleus and are involved in cell division. Centrioles are made up of nine triplets of microtubules, which are long, thin protein filaments. The microtubules are arranged in a ring around the centriole, and they help to organize the mitotic spindle during cell division.<\/p>\n<p>Centrioles are also involved in the formation of cilia and flagella.
