Answer:
Step-by-step explanation:
The cytoskeletal component responsible for acting as a highway for positioning organelles and facilitating the beating motion of flagella is the microtubules. Microtubules are hollow tubular structures composed of the protein tubulin. They form a dynamic network within the cytoplasm and provide structural support to the cell. They also serve as tracks or highways for the movement of vesicles, organelles, and other cellular components.
In addition to transporting cellular cargo, microtubules play a crucial role in the beating motion of flagella and cilia. Flagella are long, whip-like structures that extend from certain cells and are involved in cell motility. The microtubules in the flagella form a 9+2 arrangement, where nine peripheral microtubule doublets surround a central pair of microtubules. The coordinated sliding of these microtubules by motor proteins generates the bending and waving motion of the flagella, allowing the cell to move or propel substances across its surface.
Overall, microtubules act as essential components of the cytoskeleton, providing both structural support and functional capabilities for cellular organization and movement.
