Final answer:
Microtubules are the cytoskeletal structures that extend from the centrosome to the cell periphery, crucial for cell shape, organelle movement, and cellular division processes.
Step-by-step explanation:
The cytoskeletal structures that grow out from a centrosome toward the cell periphery are B. Microtubules. Microtubules are composed of alpha and beta-tubulin polymers that form hollow cylinders. These cylinders twist around each other to create the structure responsible for maintaining the cell's shape, moving organelles within the cell, and forming the mitotic spindle during cell division. Moreover, microtubules are integral parts of cilia and flagella, aiding in cellular movement.
The cytoskeletal structure that grows out from a centrosome toward the cell periphery is Microtubules.Microtubules are composed of alpha and beta-tubulin and radiate outwards from the centrosome. They help the cell keep its shape, hold organelles in place, and allow them to move around the cell. Microtubules also form the mitotic spindle during cell division and make up parts of cilia and flagella.
