Final answer:
The cytoskeleton is composed of microtubules, intermediate filaments, and microfilaments. These fibers perform important functions in the cell, such as maintaining cell shape, promoting cellular movement, and aiding cell division.
Step-by-step explanation:
The cytoskeleton is composed of three types of fibers: microtubules, intermediate filaments, and microfilaments. These fibers play crucial roles in the cell, including maintaining cell shape and structure, promoting cellular movement, aiding cell division, and securing organelles in specific positions. Microtubules are the thickest fibers and guide organelle movement, while microfilaments are the thinnest fibers and function in moving cellular components. Intermediate filaments have an intermediate diameter and help maintain cell shape and anchor organelles.
