The organelle that aids in cell division and is part of the cytoskeleton is the centriole.

Centrioles are cylindrical structures found in animal cells, typically located near the nucleus. They consist of nine sets of microtubule triplets arranged in a circular pattern. Each triplet contains one complete microtubule and two incomplete microtubules. The centrioles are surrounded by a protein-rich material called pericentriolar material.

Centrioles have a crucial role in cell division, specifically in the formation of the mitotic spindle during cell division. The mitotic spindle is a crucial structure required for the proper separation of chromosomes during both mitosis (cell division in somatic cells) and meiosis (cell division in reproductive cells).

During the cell division process, the centrioles replicate themselves, and the duplicated pairs move to opposite poles of the cell. They then serve as the organizing centers for the assembly of the mitotic spindle. Microtubules extend from the centrioles, forming spindle fibers that attach to the chromosomes and facilitate their movement and separation.

In addition to their role in cell division, centrioles are also involved in the formation of cilia and flagella. These are hair-like structures that extend from the cell’s surface and contribute to processes such as cell movement and sensory perception.

In summary, centrioles are vital organelles that aid in cell division, as they play a crucial role in the assembly of the mitotic spindle. They organize and guide the movement of chromosomes during cell division, ensuring accurate separation and distribution of genetic materials to daughter cells.
