Microtubules are cyclindrical shaped polymers that help maintain and stabilize cell structure. They also have a major role in the transportation of molecules within the cell. They are part of the cytoskeleton, and the cytoskeleton is considered to be an organelle. The microtubules are only a fraction of an organelle under the cytoskeleton.
Only the plasma membrane is made of phosophlipids as a semipermiable membrane. No other structures are made from it. There are, however, organelles which are surrounded by a plasma membrane. These include nucleus, mitochondria, peroxisomes, lysosomes and chloroplasts (in plants).
The centriole is the organelle that has 13 rows of tubulin dimers around an empty central core. It plays a key role in cell division by organizing the mitotic spindle apparatus.
The organelle you are referring to is the centrosome. It contains a pair of centrioles and helps organize microtubules during cell division to form the mitotic spindle, which is essential for segregating chromosomes.
The organelle that aids in cell division is the centriole. Centrioles are responsible for organizing the microtubules that make up the mitotic spindle during cell division, helping to separate chromosomes into two daughter cells.
The centriole is a paired organelle found only in animal cells. It is located near the nucleus in the centrosome, and acts as an organizing center for microtubules. The centrioles helps in the organization of Mitotic spindle fibers and in the completion of Cytokinesis.

No, they are not. Microtubules for the basis of transport within the cell.
(: Centriole :)
The centrioles are organelles in the cell that sends out microtubules that connect to the DBA during the metaphase. These centrioles determine the position of the nucleus and plays a crucial role in the spatial arrangement of the cell.
