Centrosome: Structure and Function

The centrosome is a small, organelle-like structure found in the cytoplasm of animal cells. It plays a crucial role in cell division and organization of the cytoskeleton.

Structure

The centrosome is composed of two cylindrical structures called centrioles, which are made up of microtubes arranged in a specific pattern. The centrioles are surrounded by a protein-rich matrix called the pericentriolar material.

Function

The main function of the centrosome is to organize the mitotic spindle during cell division. The centrosomes serve as the main microtubule-organizing centers (MTOCs) in animal cells. They also play a role in the formation of cilia and flagella, which are important for cell motility and sensory functions.
