Intermediate filaments commonly work in tandem with microtubules, providing strength and support for the fragile tubulin structures. All cells have intermediate filaments, but the protein subunits ...

This is a picture of Drosophila melanogaster (fruit fly) sperm, showing the growing flagella (in green). The structure at the base of flagella is shown in red, and blue marks the DNA of each sperm ...

It consists of a pair of centrioles — structures analogous to the basal bodies of cilia and flagella — surrounded by pericentriolar material from which microtubules are nucleated and anchored.
