Solution
All the statements provided are correct.
i. The cytoskeleton does include structures that function to maintain the shape of the cell, motility, and extracellular transport functions of the cell. ii. The cytoskeleton is indeed composed of three main components: Microtubules, Microfilaments, and Intermediate filaments. iii. Microtubules do grow outward from the microtubule organizing center centrosome and are involved in chromosome separation during cell division & motility of cilia. iv. The centrosome is composed of two centrioles placed perpendicular to each other & each centriole is composed of microtubules arranged as nine peripheral triplets. v. Microfilaments are comprised of the protein actin & Actin constitutes with myosin involved in muscle contraction.
Therefore, none of the statements are incorrect.
