Answer:
cytoskeleton
Step-by-step explanation:
Eukaryotic cells contain proteins called the microfilaments (actin),microtubules( tubulin) and the intermediate filaments that are collectively coined as the cytoskeleton. The mechanical strength of the cell that is provided is due to protein scaffolding in the cytoskeleton. In addition, protein scaffolding can also determine the shape of the cell. This therefore shows that cytoskeleton provide both structure and support to cells.
