Centrioles works during cell division as there is a single centrioles present in our cell but it gets double in interphase ,then in prophase two centrioles start to move in opposite ends and after reaching form spindle then spindle arrange doubled chromosomes in it and then centrioles divide chromosomes by attracting them as a result nucleus get divide.
the centrosome is a cellular organelle which contains two perpendicular lying centrioles surrounded by aster rays. the centrioles are made up of tubulin protein arranged in a 9+2 manner which functions for the formation of microtubules which further form flagella and cilia like structures along with the cytoskeletal structure of the cell for cyclosis or cytoplasmic movements.
the aster rays form the spindle fibres during the process of cell division in an animal cell. the centriole also function for the elongation of cells like nerve cells in humans and is lost during the process so the nerve cells lose the feature of cell division.
There are two main functions of cetrioles i.e 1)It is help with cell division in animal cells.It help in formation of the spindle fibers that separate the chromosomes during cell division. 2)It plays important role in celiogenesis means it helps in the formation of cilia and flagella on the surface of the cells.
