Centrioles are found only in animal cells. In plants the nuclear and cell division are mainly localized in special regions called meristems. This rapidly dividing region will either elongate the tips of stems and roots or expand the girth of the plant, in animals, cells divide everywhere, all the time. The division process is essentially the same for plants and animals. The main difference comes when it is time for cytoplasmic division. A plant cell builds a new cell wall to divide its two daughter cells, and an animal cell will pinch in two, or cleave.
