Final answer:
The cytoskeleton is composed of microtubules, microfilaments, and intermediate filaments. Microtubules help with cell division and movement, while microfilaments provide rigidity and facilitate cellular movements. Intermediate filaments have a structural role in maintaining cell shape and stability.
Step-by-step explanation:
The cytoskeleton is composed of three main components: microtubules, microfilaments, and intermediate filaments. Each component performs different functions in the cell.
They are also the structural elements of centrioles, flagella, and cilia.
Microfilaments provide rigidity and shape. They can interact with motor proteins to change the shape of the cell or move organelles within the cell.
Intermediate filaments have a mainly structural role, bearing tension and anchoring the nucleus and other organelles in place. They help maintain cell shape and stability.
