Detailed explanation-1: -Complete answer: Cell division is initiated by centrosomes. Prophase is the initial phase of mitosis.

Detailed explanation-2: -Final Answer:-Cell division is initiated by centrosomes.

Detailed explanation-3: -And those centrioles are very important for cell division. So when the cell is going to divide, those centrioles go to opposite ends of the nucleus. And when the chromosomes are condensing to undergo mitosis, the centrioles form the areas that mitotic spindle forms from.

Detailed explanation-4: -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-5: -Centrioles-Organizing Chromosomes They are put to work in both the process of mitosis and the process of meiosis. You will usually find them near the nucleus but they cannot be seen when the cell is not dividing. And what are centrioles made of? Microtubules.
