Final answer:
The cytoskeleton provides structural support to the cell, facilitating its shape, movement, intracellular transport, and division. It consists of microfilaments, intermediate filaments, and microtubules, and is found in both prokaryotic and eukaryotic cells.
Step-by-step explanation:
The correct statement about the cytoskeleton is: B) It provides structural support to the cell. The cytoskeleton is essential for maintaining the cell's shape, securing organelles in specific positions, enabling cellular motion, and playing a role in both intracellular transport and the cell division process.
The cytoskeleton is not composed of lipids and phospholipids, which refutes statement A. Furthermore, statement C is incorrect because the cytoskeleton is found in both prokaryotic and eukaryotic cells, not just in prokaryotic cells. Lastly, statement D is inaccurate as the main function of the cytoskeleton is not energy production, but rather providing structural integrity and facilitating various transport and motility functions. For energy production, cells rely on organelles known as mitochondria.
Three primary types of fibers constitute the eukaryotic cytoskeleton: microfilaments, intermediate filaments, and microtubules. These structures are highly dynamic and continually assemble and disassemble according to the needs of the cell.
