Plant cells do not use centrioles in mitosis, many don't even use centrosomes! Despite this lack of centrosomes and centrioles, these plant cells are still able to bundle and organize their microtubules into a spindle. How plant cells are able to do all this is not clear, but this is also what is seen in meiotic divisions in animal cells, such as in the early divisions in mouse embryonic cells.

I agree with birchardv here...........we need the rest of the problem, and you would learn a lot more if you did the homework yourself.  But do whatever floats your boat.  Add the rest of the problem and I'll get back to you.\n\nOkay Chemist, this problem is really long; if you want a good answer with plenty of steps, I'll need more room.  Email me and I'll send you the solution.

Sounds like a Math/Science type question to me. Why are you posting it here?\n\nBesides, I have the the slightest idea.

This seems more like a physics question than a chemistry question.  I would try posting this in the physics section- someone will be able to help you there!

This may possibly be the easiest question anyone has ever asked on this forum. If you can't figure this out yourself, you really need to do more homework!! BTW, that is one freakin' tall sheep!!
