Centrioles are among the largest protein-based structures found in most cell types, measuring approximately 250 nm in diameter and approximately 500 nm long in vertebrate cells.
In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells. A bound pair of centrioles, surrounded by a highly ordered mass of dense material, called the pericentriolar material, makes up a structure called a centrosome. Centrioles are not present in all eukaryotes; for example, they are absent from conifers, flowering plants and most fungi, and are only present in the male gametes of charophytes, bryophytes,
Apr 09, 2020 · Centrioles are small sets of microtubules that are set up in a particular pattern. Nine different microtubule groups exist, and when two centrioles appear adjacent to one another, they sit at 90-degree angles. At the time of cellular division, the centrioles move toward opposing ends o the nucleus, and threads appear connected to them.
Equator is just the term used to explain where the chromosomes line up during metaphase and the poles are just the two ends of the cell where the centrioles migrate to before the chromosomes do. But don't expect to see anything at the poles of cell, no more than you would if you went to the poles of Planet Earth.
This volume combines the latest information on the structure, molecular composition, and roles of Golgi and centriole in various cellular functions and diseases. The better understanding of the Golgi–centriole interactions may lead to the development of novel therapies for the treatment of various diseases, including cancer.

It's recommended to have an organizational structure in place to accurately define the activities in a project. Projects have many activities, from task allocation to budgeting and everything in-between.
