Why do animal cells have centrioles but plant cells do not?

Animals have centrioles to form spindle fibers during prophase. The centriole divides cells. Plants dont have them because they have microtubules instead. they dont need centrioles. Plants are capable of forming a circular loop of microtubules around the future plane of division prior to prophase called the preprophase band, rather than centrosome. Basically - plants don't need it. They have a different way of cell division.
