Answer:
two (a pair)
Explanation:
Centrioles are the pair of hollow cylinders that are located near the nucleus in the cytoplasm in a non-dividing cell. Two centrioles together make a centrosome. Centriole duplication occurs before cell division as the duplicated centrioles take part in the formation of the spindle apparatus. However, cytokinesis distributes one pair of centrioles to each daughter cell. Therefore, after cytokinesis, two centrioles are present in each daughter cell.
