Term Detail
GO term:cilium
Synonym: eukaryotic flagellum
Synonym: flagellum
Synonym: microtubule-based flagellum
GO id:GO:0005929
Definition:A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.
CommentsNote that we deem cilium and microtubule-based flagellum to be equivalent.
