Cycads are some of the only plants to have them, and they are unique to eukaryotes. Like a longer structure, they have a 9+2 arrangement of constituent structures which make up the axoneme. The Fallopian tubes use them to conduct eggs from ovary to uterus and the trachea has a lining of them for cleaning purposes. Rotifers have a crown of them, which in some species makes them spin like wheels, and several of them are also found on paramecium. For 10 points, identify these short organelles which allow many eukaryotic cells to move.
