Function of
centrioles
An organelle that forms a
spindle-shaped structure of protein fibers on which the chromosomes move during
nuclear division are called the centrioles. Centrioles are part of the animal
cell organelles. Hence, they are a small part of the microtubules organized and
set in a particular course. Microtubules include 9 sets. Centrioles contain a
cylindrical structure, packed with protein which is described as tubulin. Found
mostly in eukaryotic cells beside the nucleus.
