What is the role of the cytoskeleton in a cell?

The cytoskeleton plays a crucial role in providing structure and support to a cell. It is a dynamic network of fibers composed of microtubules, intermediate filaments, and microfilaments. This framework not only maintains the cell's shape but also aids in the organization of the cell's internal components, including organelles. Additionally, the cytoskeleton contributes to cell motility and division. By interacting with various proteins, it can change shape and allow for movement, making it essential for processes such as cytokinesis during cell division, as well as enabling cells to respond to their environment.

While other options mention important cellular functions, they do not specifically highlight the primary function of the cytoskeleton, which is structural support and maintenance of cell integrity.
