Cilia are present on single-celled organisms such as paramecium, a tiny, free-living protist that can be found in fresh water ponds. Cilia are also found, in modified form, in tissues such as the kidney and pituitary gland.
Figure legend:. Eukaryotic flagella have a complex internal arrangement of microtubules that slide past one another. Energy is used in this process. Cilia are slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells multiple or single.
You should start with the distinction between prokaryotic flagella which are totally different in structure and mechanism of beating! Then you could say about differences between eukaryotic cilia and flagella but actually the current consensus in the field is that these 2 organelles were historically called differently because of some morphological features but they are very close to each other from evolutionary perspective and hence represent just 2 variants of the same structure.
Save my name and email in this browser for the next time I comment. This video explains the difference between cilia and flagella, as well as the function and structure of these cell organelles. Eukaryotic motile cilium and flagellum are structurally identical.
Each is a bundle of nine fused pairs of microtubule doublets surrounding two central single microtubules. The movement of both cilia and flagella is caused by the interactions of these microtubules.
In non-motile or primary cilia the two central single microtubules are absent. In prokaryotes cells the flagella are filamentous protein structures composed of flagellin. There two types of cilia - motile and non-motile or primary cilia.
Lack of proper functioning of cilia and flagella can cause several problems in human beings. For example,. Share this comparison:. If you read this far, you should follow us:. Diffen LLC, n. All I would say is that eukaryotic flagella and bacterial flagella are two totally different entities that cannot be compared.
