WebScience Biology Which statement about the cytoskeleton is incorrect? Microtubules are hollow tubes of protein that provide structural support. Plant cells lack a cytoskeleton because they have a rigid cell wall. Intermediate filaments are more permanent structures in cells compared to microfilaments and microtubules. WebAs their name implies, microtubules are small hollow tubes. Polymerized dimers of α-tubulin and β-tubulin, two globular proteins, comprise the microtubule's walls (Figure 4.25). With a diameter of about 25 nm, microtubules are cytoskeletons' widest components. They help the cell resist compression, provide a track along which vesicles move ...
