Microtubules, microfilaments and intermediate filaments:
| 1. | are ribonucleoproteins. |
| 2. | are part of cytoskeleton in both eukaryotic and prokaryotic cells. |
| 3. | are involved in many functions such as mechanical support, motility, maintenance of the shape of the eukaryotic cell. |
| 4. | are always deposited on cell surface and are never found in the cytoplasm. |
Subtopic: Cytoskeleton | Cilia & Flagella | Microbodies |
