Functions of centrioles

Describe briefly the functions of centrioles?

E

Expert

Verified

Scientists assume that the centrioles encompass something do with the cell division and spindle formation, however the exact function is unknown, especially as plants do not contain centrioles and they form anastral spindle fibers (that is, cytoplasmic strands or the microscopic tubules) and experience cytokinesis through cell-plate formation.
