Centrioles are small, cylindrical structures that exist in pairs within the cell. They are primarily involved in cell division and have a crucial role in the formation of the spindle fibers during mitosis (cell division) and meiosis (reproduction process). Centrioles help in organizing the microtubules that make up the spindle fibers, which are responsible for separating the duplicated chromosomes and ensuring equal distribution into daughter cells. Additionally, centrioles are involved in the formation of cilia and flagella, hair-like structures that aid in cell movement and sensory functions.
