Microfilaments, also known as actin filaments, provide the structural basis for cell shape change and cell movement, while myosin is responsible for the contraction of these filaments. Both microfilaments and myosin are important in various types of cell movement, such as muscle contraction, cytokinesis, and amoeboid movement. Intermediate filaments, on the other hand, provide mechanical strength and stability to cells and their organelles, but they are not directly involved in cell movement. Microtubules, another type of cytoskeletal protein, play a significant role in intracellular transport, chromosome segregation during cell division, and cilia/flagella movement, but they are not the primary cytoskeletal component for cell movement.
