Verified step by step guidance

Understand the components of the cytoskeleton: The cytoskeleton is composed of microtubules, intermediate filaments, and actin filaments, each with distinct functions.

Identify the function of microtubules: Microtubules are involved in maintaining cell shape, intracellular transport, and chromosome separation during mitosis, not muscle contraction or cell-cell adhesion.

Identify the function of intermediate filaments: Intermediate filaments provide mechanical support to cells, helping them withstand stress and maintain their integrity.

Identify the function of actin filaments: Actin filaments are involved in muscle contraction, cell movement, and also play a role in cytokinesis during cell division, but not directly in chromosome separation during mitosis.

Match the correct component to its function: Based on the functions identified, intermediate filaments are correctly matched with providing mechanical support.
