What is the primary function of the cytoskeleton in a cell?

The primary function of the cytoskeleton in a cell is indeed to determine the shape and mechanical strength of the cell. The cytoskeleton is a complex network of protein filaments and tubules that extends throughout the cytoplasm and provides structural support. It plays a crucial role in maintaining the cell's shape, allowing it to withstand various mechanical stresses.

Additionally, the cytoskeleton is involved in various cellular processes such as cell division, intracellular transport, and the movement of cilia and flagella. By providing a framework for the cell, it helps ensure proper organization of organelles and aids in transportation within the cell, but its foundational role revolves around maintaining structural integrity and shape. This aspect distinguishes it from functions performed by other cellular components, such as those responsible for storing genetic information or synthesizing proteins.
