cen·tri·ole

 (sĕn′trē-ōl′)
n.
One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.

[New Latin centriolum, diminutive of Latin centrum, center; see center.]

centriole

(ˈsɛntrɪˌəʊl)
n
(Genetics) either of two rodlike bodies in most animal cells that form the poles of the spindle during mitosis
[C19: from New Latin centriolum, diminutive of Latin centrum centre]

cen•tri•ole

(ˈsɛn triˌoʊl)

n.
a small cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides perpendicularly during mitosis.
[< German Zentriol (1895), derivative of Latin centrum center]

cen·tri·ole

(sĕn′trē-ōl′)
Either of a pair of cylinder-shaped bodies found in the centrosome of an animal cell. During mitosis, the centrioles move apart to help form the spindle, which then distributes the chromosomes in the dividing cell. See more at cell, meiosis, mitosis.

centriole

1. Either of two organelles near the nucleus involved in cell division.
2. One of a group of tiny tubules near the nucleus of a cell. Centrioles play a part in cell division. See mitosis.
