Centrosome

A centrosome is a specific part of the cell specific to animal cells.

Structure of the centrosome

The centrosome composed of two centrioles, perpendicular to each other which are composed of microtubules. It is a specific part found in cytoplasm and is considered to be an organelle although is not delineated by a lipid membrane.

Function of the centrosome

The centrosome is a centre which organises microtubules (or MTOC). It is therefore responsible for the formation of the microtubule mitotic spindle during cell division on which the chromosomes move.

The MTOC of plant cells are different.
