Centrosomes are organelles that serve as the main microtubule-organizing centers for animal cells. Centrosomes are made up of two, barrel-shaped clusters of microtubules called “centrioles” and a complex of proteins that help additional microtubules to form.
In cell biology, the centrosome (Latin centrum 'center' + Greek sōma 'body') (archaically cytocentre [1]) is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell, as well as a regulator of cell-cycle progression. The centrosome provides structure for the cell.
A centrosome is a cellular structure involved in the process of cell division. Before cell division, the centrosome duplicates and then, as division begins, the two centrosomes move to opposite ends of the cell.
What is the main function of a centrosome? A centrosome comprises two microtubule rings known as centrioles. Its main function is to organize the microtubules and provide a structure to the cell.
The centrosome plays several crucial functions in animal cells. Main Purpose. It is the major microtubule-organizing center in animal cells. The centrosome thus helps protein dimers to assemble into microtubules, forming the mitotic spindle in dividing cells.
Centrosomes are cellular components that appear like a disc in shape and are internally built by microtubule components and play important role in cell division. Centrosomes are double or a pair of centrioles along with microtubule-organizing center (MTOC) with the pericentriolar matrix.
Functions of Centrosomes. In addition to their role in spindle formation, centrosomes play other important roles in animal cells: Formation of the network of microtubules that participate in making the cytoskeleton. Signaling that it is o.k. to proceed to cytokinesis.
