Detailed explanation-1: -The centrosome is the major microtubule-organizing center in the cell. During interphase the centrosome is responsible for creating a microtubule array and during mitosis it assists in bipolar spindle assembly.

Detailed explanation-2: -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-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: -Centrioles recruit and organize pericentriolar material. As a result, centrioles dominate microtubule organization and spindle assembly in cells born with centrosomes. Centrioles duplicate in concert with chromosomes during the cell cycle.

Detailed explanation-5: -All animal cells have two centrioles. They help the cell during cell division. They work during the process of mitosis and meiosis.
