Discussion of all aspects of cellular structure, physiology and communication.
are you sure you do?
Current models have been unable to find what is it exactly that centrioles do. plant cells not have centrioles and they can generate spindles just fine. if you remove the centriols from an animal cell with a microlaser, a spindle will nevertheless form. this is not to say that centrioles are useless. nothing is useless. but we don't really know what they do. our best guess is that they "somehow" help direct the spindle against the axis of the cell.

Thanks for providing links,they are very helpful.
I am also shearing something about function of a centriole.
Centrioles line up the chromosomes inside the cell and then they pull the chromosomes apart during cell replication.
Structure - nine triplets of microtubules form one centriole
- two centrioles form one centrosome
Function - forms spindle fibres to separate chromosomes during cell
but didn't the question ask the function
but anyways when i was in the middle school even i knew what a centriole and it's function (for cell division) but never knew how?
and another thing i never boasted . but it's okay. when the questioner asked he meant to even know the finer details. i hope;)
it isn't what you do that matters but it is how you do it
Here's an excellent resource on the possible role of centrioles in cellular intelligence:

From what I know about the topic, a cell can divide without centrioles but cannot develop into an animal due to loss of migration behavior that makes their cells so much more "alive" in comparison to a vegetable that can do fine without a pair of them to help divide the cell and other things:
Centriole is a structure found in eukaryotic animal cells. Plant cells and fungi do no contain centrioles. Centriole is the part of the cell, which acts as the center for producing microtubules, which are the component of cytoskeleton. Cytoskeleton is the skeleton of the cell that provides both shape and structure to a cell. Animal cells contain 2 centrioles, which together form the structure, centrosome. In other words, the centrioles are found within the centrosomes, which is a small region in the cytoplasm near the nucleus. Within the centrosomes, the two centrioles are positioned in such a way that both are perpendicular to each other. Like other structures of a cell, centrioles too perform several important functions. Below here is a brief discussion about the centriole function and structure in the study of biology.
it is one of the organells in a cell which generates exoskelleton(mitotic spindle in the process of cell division) in our cell which are part of the mitotic and miosis process
i recently read that even in mitosis the mitotic spindles don't have an impact meaning that even if there is no mitotic spindle the chromosomes will migrate to opposing poles (i am assuming that you know what is going on in cell division)
