Centrioles are present in the cells of most eukaryotes, for example those of animals. However, they are absent from conifers (pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and ginkgo.[2][3]
Most centrioles are made up of nine sets of microtubule triplets, arranged in a cylinder. Deviations from this structure include crabs and Drosophila melanogaster embryos, with nine doublets, and Caenorhabditis eleganssperm cells and early embryos, with nine singlets.[4][5]
Edouard van Benedenand Theodor Boveri made the first observation and identification of centrioles in 1883 and 1888 respectively,[6][7] while the pattern of centriole duplication was first worked out independently by Etienne de Harven and Joseph G. Gall c. 1950 [8][9] The main function of centrioles is to produce ciliaduring interphase and the aster and the spindle during cell division.
