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.

What organelle has 13 rows of tubulin dimers around an empty central core?
microtubules
Which organelles are not surounded by a membrane?
The ribosome is an organelle that is not surrounded by a membrane.
What is the function of the centrioles in the cell?
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.
What organelle is responsible for movement and support of the cell?
Cell move by use of flagella, a thread like locomotor appendages extending outward from the plasma membrane and cell wall. Bacterial or micorbial flagell are the best studied and is known as of physiology and anatomy of flagella is concerned.It is formed of flagellin protein.
Which cytoskeletal element radiates from the cell center?
Microtubules radiate from the cell center.
What organelle is absent in plant cell?
microtubules
A nonmembranous organelle of two bundles of microtubules?
centrioles
What organelle has short extensions of the cytoskeleton used for movement?
microtubules
Organelle made of long microtubules to propel the cell?
basal body
Cell organelle is the transport system for the cell?
No, they are not. Microtubules for the basis of transport within the cell.
What organelle has two short microtubules at right angles and have an active role in mitosis?
centriole
What organelle has 13 rows of tubulin dimers around an empty central core?
microtubules
What is an organelle that is composed of two short microtubules at right angles to each other?
(: Centriole :)
Which organelle is responsible for cell division?
The organelle involved in cell division in animal cells is called centriolles.
What organelle is not found only in plants?
nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, microtubules
