What is centrioles?
A centriole is a small structure made of microtubules which exists as part of the centrosome, which helps organize microtubules in the body. A centriole is the main unit that creates and anchors microtubules in the cell. Typically, a eukaryotic cell has one centriole that is at a right angle to a second centriole in the centrosome. Microtubules extend from the each centriole, and use the centriole as an anchor for the base of each microtubule. Each cell may have hundreds or thousands of microtubules that extend to various parts of the cell. During normal cell functions, motor proteins attach to both the microtubules and an item to be transported. The motor proteins crawl along the microtubules, dragging whatever substance or compartment with them. Not all cells contain centrioles, and other methods are used for creating microtubules.
