Answer:
They are thick, strong and made up of thousands of tubulin which are spiral in shape.
Explanation:
In eukaryotic cells, they have microtubules which are fibres serving as tracks for cell to cell transport and regulate the shape of a cell.
Microtubules are different from other cytoskeletal filaments because they possesses a cylindrical shape with the tube having a larger diameter of 20-25 nm as compared to microfilament that have a diameter of 3-6 nm.
Microtubules are made of subunits of proteins called tubulin named alpha and beta that is not present in other cytoskeletal filaments.

Take for example the group of prokaryotes against eukaryotes. They may be similar in a way that they contain cells with organelles such as mitochondria, ribosomes, cytoplasm, and many more. But they may differ in the presence of a cell membrane and a nucleus. Eukaryotes have cell walls and a nucleus, while prokaryotes don't have.
