Final answer:
The cytoskeleton is a network of microfilaments, intermediate filaments, and microtubules found throughout the cytoplasm of eukaryotic cells. These protein fibers help maintain cell shape and enable cell motility. Motor proteins interact with microtubules and microfilaments to generate force and facilitate cellular movement.
Step-by-step explanation:
The cytoskeleton is a network of microfilaments, intermediate filaments, and microtubules found throughout the cytoplasm of eukaryotic cells. These protein fibers help maintain the shape of the cell, allow movement of cytoplasm, vesicles, and cells within multicellular organisms. Microfilaments and microtubules are involved in cell motility, allowing the cell to change shape and move. Motor proteins, such as myosin, dynein, and kinesin, interact with microtubules and microfilaments to generate force and facilitate cellular movement.
