Centrosomes are small, cylindrical structures found in the cells of animals and some plants. They play a crucial role in organizing microtubules, which are part of the cell's cytoskeleton. Each centrosome consists of two centrioles, which are arranged at right angles to each other. During cell division, centrosomes help to ensure that chromosomes are properly separated into the daughter cells. In addition to their role in cell division, centrosomes are involved in various cellular processes, including maintaining cell shape and facilitating intracellular transport. They are essential for the formation of the mitotic spindle, which is necessary for accurate chromosome segregation during mitosis and meiosis.
