Question

describe the structure of centreole and function??

Answer 1

There are two main functions of centrioles that we will focus on. The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis).

Answer 2

All animal cells have two small organelles known as centrioles. The centrioles help the cell to divide. Centrioles are seen the process of mitosis and meiosis. The centrioles together are typically located near the nucleus in the centrosome. Centrosomes is granular mass that is the organizing center for the microtubules. The position of the centrosome within the centrosome is at right angles to each other. Centrioles are made of nine bundles of microtubules, that are arranged in a ring. 


The centrioles play a major role in cell division. In animal cells the centrioles play a major role in cell division but the plant cells have the ability to reproduce even without the centrioles. In certain animal cells, like the female oocytes, some cells have have shown successful division even in the absence of the centrioles. The absence of centrioles causes divisional errors and delays in the mitotic process. It is consequently suggested that centrioles have evolved as a cell refinement, that makes mitosis a more efficient and lesser error prone process.
