Motile cilia (also interchangeably called "flagella") are conserved organelles extending from the surface of many animal cells and play essential functions in eukaryotes, including cell motility and environmental sensing. (emory.edu)
Flagella and motile cilia have highly ordered and precisely assembled superstructures, called axonemes. (rupress.org)

Unicellular eukaryotes are sometimes called protists. (wikipedia.org)
Flagella, such as in spermatozoans and many single-celled protists, are responsible for locomotion by generating two-dimensional "arc-line" waveform beats (Gibbons, 1981). (genevo-rtg.de)
Organisms such as animals, plants, fungi, and protists are examples of eukaryotes because their cells are organized into compartmentalized structures called organelles, such as the nucleus. (edu.vn)
Animals , plants , fungi , and protists are eukaryotes ( Template:IPAEng or Template:IPAEng ), organisms whose cells are organized into complex structures enclosed within membranes . (wikidoc.org)

A flagellum (plural, flagella ) is a long, whip-like projection or appendage of a cell composed of microtubules (long, slender, protein tubes) and used in motility. (newworldencyclopedia.org)
Eukaryote flagella are similar to cilia -another structure that extends out from the surface of cell and is used for movement-in that both are composed of nine pairs of microtubules (nine microtubule doublets) arranged around its circumference and one pair of microtubules (two microtubule siglets) running down the center, the 9 + 2 structure (Towle 1989). (newworldencyclopedia.org)
However, unlike centrioles, cilia and flagella feature a centre pair of microtubules, leading to the term "9 + 2 axoneme" for the total structure. (risingacademy.org)
Cilia or flagella are composed of nine doublet microtubules surrounding a pair of singlet microtubules called the central pair (CP). (go.jp)
Kinesin-13, an end depolymerizer of cytoplasmic and spindle microtubules, also affects the length of cilia. (emory.edu)

Large motor complexes, the ciliary dyneins, are present on ciliary outer-doublet microtubules and drive movement of cilia. (emory.edu)

Ciliates like paramecium, vorticella, and ophrydium move in water with the help of their numerous small hair like structures called the cilia. (gardenerdy.com)
The ciliates are so named because of the cilia, small hairs that are distributed over the entire body. (rightcrowdevents.com)

The structural similarity of cilia and eukaryote flagella, and the substantial differences between flagella in eukaryotes and prokaryotes, is such that some authorities group cilia and eukaryote flagella together and consider cilium simply a special type of flagellum-one organized such that many flagella (cilia) may work in synchrony (Patterson 2000).
