Cytoskeleton and microtubules

WebMicrotubules As their name implies, microtubules are small hollow tubes. With a diameter of about 25 nm, microtubules are cytoskeletonsʼ widest components. They help the cell resist compression, provide a track along which vesicles move through the cell, and pull replicated chromosomes to opposite ends of a dividing cell (figure 18.5). WebA cytoskeleton provides structure to the cell and connects to every part of the cell membrane and every organelle. Microtubules and microfilaments together allow the cell to hold its shape, and move itself and its …
