Verified step by step guidance

Begin by understanding the function and composition of the cytoskeleton. The cytoskeleton is a network of protein fibers within the cell that provides structural support, facilitates intracellular transport, and plays a role in cell division and movement.

Identify the components of the cytoskeleton. The main components are microfilaments, intermediate filaments, and microtubules, all of which are composed of proteins, not carbohydrates.

Evaluate each statement given in the problem. The statement 'The cytoskeleton is involved in intracellular transport' is true, as microtubules and motor proteins facilitate the movement of organelles and vesicles within the cell.

Consider the statement 'Microtubules are a component of the cytoskeleton.' This is true, as microtubules are one of the three main types of protein fibers in the cytoskeleton.

Analyze the statement 'The cytoskeleton provides structural support to the cell.' This is true, as the cytoskeleton maintains the cell's shape and offers mechanical support. The false statement is 'The cytoskeleton is composed solely of carbohydrates,' as it is actually composed of proteins.
