Cilia are hairlike projections of paramecium made of microtubules.
Cilia is from the Latin for eyelash. Cilia are made of small tubes called microtubules. These microtubes are made of proteins including molecular motor proteins. The cilia are able to move and organisms such as paramecium beat their cilia in unison allowing them to move through the watery environments where they live.

The video below shows a number of paramecium using cilia to move while feeding.
