What is the function of the cytoskeleton?

The cytoskeleton is an important network within the cell that consists of various protein filaments and tubules. Its primary function is to provide structure and shape to the cell, which helps maintain its overall integrity. This structural role is crucial for the cell’s ability to withstand external forces and maintain its shape, much like a skeleton supports the body of an animal.

Additionally, the cytoskeleton plays a significant role in cell movement. It facilitates the movement of organelles within the cell and is involved in processes like cell division and muscle contraction. The dynamic nature of the cytoskeleton allows it to reorganize quickly in response to changes, which is vital for cellular activities.

While the other options, such as nutrient storage, energy production, and DNA replication support, are also essential processes within the cell, they do not relate directly to the main roles of the cytoskeleton. The cytoskeleton specifically focuses on structural integrity and movement rather than these other functions.
