Why do animal cells have centriole but plant cells do not?
Mamont248 [21]
<span>Animals have centrioles to form spindle fibers during prophase. The centriole divides cells. Plants do not have them because they have microtubules instead; they do not need centrioles.

Basically- plants don't need it. They have a different way of cell division.</span>
