centrioles? Buy new books buddy. Centrioles are not absolutely necessary for any cell. Plant cells don't have them at all. And if you distroy them in an animal cell, the cell still divides by mitosis.

NO. experimental procedures have shown that if you use a laser to distroy the centrioles of an animal cell it will still divide.
Actually, according to Molecular Biology of the Cell a spindle can form with no problems even without centrosomes. It is called a bipolar spindle, and it has provided evidence that chromosomes play an active role in spindle formation...
