Question
State the role of centrioles in cell division.

Answer

Centrioles play an important role in formation of spindle during cell division. They organise the mitotic spindle and thus, help in the completion of cytokinesis. They generate the cell's cytoskeleton and help in the formation of the mitotic spindles. In organisms with flagella and cilia, the position of these organelles is determined by the mother centriole, which becomes the basal body.
