message: The mechanism of Intraflagellar transport constructing cilia has now become a focus of attention, as discussed in some detail here. Apparently a Jekely and Arendt (2006) cilium evolution paper p. 193 describes Plasmodium falciparum as an exception that lacks IFT – "species with cilia that do not rely on IFT (in the parasite Plasmodium cilia assemble in the cytoplasm(48))". I've added a brief mention of this, using the panda's thumb link as I don't have access to the paper or the expertise to work from it. .. dave souza, talk 19:43, 6 August 2007 (UTC)

message: I totally agree.  Biology is very hard.  I thought that studying the cell was the hardest chapter.  Our teacher actually made us take a test on how to hold a microscope.--69.196.197.190 (talk) 02:18, 20 November 2008 (UTC)

message: The present article reads:
Along with flagella, they make up a group of organelles known as undulipodia.
I thought that cilia are structurally identical to flagella.  —Preceding unsigned comment added by 91.64.166.91 (talk) 12:18, 2 July 2008 (UTC)
replies: text: I am not a biologist but I had understood that to be the case also.  Someone will need to find a verifiable source to clarify it for the article.  I had understood the that both a cilium and a flagellum were structurally similar organelles but that the name given was 'flagellum' in the case of single celled organisms and 'cilia' in the case of multiple-cell organisms.  There function is similar as well, handling protein transport and, in the case of the motile cilia and most flagella, having an ability to move as well through some sort of rotor/stator protein arrangement in the basal body of the cell.

replies: text: Flagella and Cilia differ in the fact that cilia are shorter and more numerous.  They also look like hairs.  Their motion is similar to a rowboat.  Flagella look alot like sperm cells.  They have a tail that moves them along instead of hairs.  —Preceding unsigned comment added by 69.196.197.190 (talk) 02:21, 20 November 2008 (UTC)
replies: text:  I happen to be a biologist and I have always been told that eukaryotic cilia and prokaryotic flagella are mechanistically different (as can be easilly seen by looking at the artcile illustrations); also, the proteins they are made of are not homologous as far as I know. Hence, the sentence "Eukaryotic cilia are structurally identical to Prokaryotic flagella, although distinctions are sometimes made according to function and/or length" is 100% wrong!  —Preceding unsigned comment added by 140.77.192.140 (talk) 08:15, 23 July 2010 (UTC)
replies: text: Eukaryotic flagella ARE different from prokaryotic flagella. However, even within eukaryotes, both terms cilia and flagella are used to describe the structures. The terminology is considered to be interchangeable since the underlying structures are the same, but some people still use the terms differently based on the function and number of the cilia/flagella, as outlined by 69.196.197.190 (talk) above.--AaronM (talk) 11:33, 23 July 2010 (UTC)
replies: text: Yes, the sentence "Eukaryotic cilia are structurally identical to Prokaryotic flagella, although distinctions are sometimes made according to function and/or length" is 100% wrong.  I concur with anon editor 140.77.192.140.   Cheers.  N2e (talk) 18:34, 23 July 2010 (UTC)
thread_title:  cilium vs. flagellum 

message: If someone is going to write something on the scientific history, it may be interesting to know that it was discovered in 1898, and the article that is usually referenced, is "Beiträge zur Kenntnis einiger Drüsen und Epithelien" by Zimmerman in "Archiv für mikroskopische Anatomie", 9, pp. 163-168. Probably ISSN 0176-7364 or ISSN 0176-7356. I haven't been able to get it online, yet. --WvEngen (talk) 10:09, 29 July 2008 (UTC)

message: There is a misconception that primary cilia are non-motile. Primary cilia refers to the structure of an axoneme WITHOUT the central pair, i.e. 9+0. --kupirijo (talk) 12:22, 25 March 2009 (UTC)

message: The article has cilia length as 5-10 micrometres, but the length is given as 2-3 in the histology texts I have to hand [e.g., Junqueira & Carneiro]. Can someone confirm this?  —Preceding unsigned comment added by 193.1.104.2 (talk) 13:45, 9 July 2009 (UTC)
replies: text: I removed the uncited assertion that cilia length are 5-10 micrometres in the lede paragraph.  If you have a verifiable source you can cite, like a book or journal article, I hope that by all means you will correct the article with your information and add the citation.  Cheers. N2e (talk) 00:38, 21 August 2009 (UTC)
replies: text: Please but the length info back, it is roughly correct. Alberts:Molecular biology of the cell should do as a reference. Cilia are found in all 5 domains of life! So some variability in length should come as no surprise at all. In its current state the article does not state diameter, length, no scalebar, ... ~  — Preceding unsigned comment added by 79.240.227.15 (talk) 21:26, 4 March 2016 (UTC)

message: In the initial image, there is nothing labeling the axoneme. I presume that the purpose of the image is to illustrate the axoneme, but the reader would have to be an expert already to identify the axoneme in the image. 
If it's not possible to alter the labeling within the image, the subscript text needs to be expanded so as to clarify which part is the axoneme. Since I am not an expert, I leave it to the author(s) to make the changes. Thanks.  KC 20:25, 10 January 2016 (UTC)
