Describe in detail about the unicellular eukaryotes
Animal cel1.s and many types of unicellular eukaryotes contain centrioles, which are cylindrical in structure, about 0.15 m in diameter and 0.3 to 0.5 m long. They are mainly composed of microtubules and occur in pairs. It is believed that they play a role in cell division (mitosis). However, their importance is, as yet, uncertain.
