The centrosome is a cellular structure that serves as the main microtubule organizing center in eukaryotic cells, playing a crucial role in maintaining cell shape and facilitating cell division. It is typically composed of two centrioles arranged at right angles to each other, surrounded by a protein-rich matrix called the pericentriolar material. The centrosome's functions are vital during the cell cycle, particularly in organizing the mitotic spindle during mitosis.
