Detailed explanation-1: -Definition. Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope . Centrioles play a role in organizing microtubules that serve as the cell’s skeletal system. They help determine the locations of the nucleus and other organelles within the cell.

Detailed explanation-2: -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.

Detailed explanation-3: -Centrioles are responsible for organizing the spindle fibers in the mitotic spindle apparatus and are thought to participate in the completion of cytokinesis during the process of cell division.

Detailed explanation-4: -What is the role of a centriole in a cell? The centriole is concerned with the cell division. They help in the formation of spindle fibres that separate the chromosomes during the cell cycle.

Detailed explanation-5: -Centrioles help to arrange the microtubules that move chromosomes during cell division to ensure each daughter cell receives the appropriate number of chromosomes. Centrioles are also important for the formation of cell structures known as cilia and flagella.
