BIOL 266 DETAILED FINAL NOTES| CONCORDIA UNIVERSITY|UPDATED 2024/2025 UNIT 9.0 – THE CYTOSKELETON Two functions of the cytoskeleton: 1. Provides structural framework for the cell,serving as a scaffold that determines cell shape and the general organisation of the cytoplasm. 2. Responsible for the movements of the entire cells and for the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm. The cytoskeleton is composed of 3 principa...
