Former good articleCell (biology) was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

  • About the origin of the name "cell", Robert Hooke in Micrographia cites the similarity with a honeycomb, I did not find a citation of monks cells.--95.244.63.214 (talk) 16:05, 4 October 2015 (UTC)
    • Might as well use the honey comb origin story instead of the monk cell origin as the monks would have totally disagreed with the 3.5 million year random emergence of the first Cell structure as stated in the same paragraph.
  • 100 trillion cells in human body seems like a very high estimate, and I don't currently have access to the dead tree book source cited (Lodish, Molecular Cell Biology). Most text books seem to put this number below 50 trillion (and as low as 5 trillion, showing the range of estimation in textbooks.) A recent comprehensive study at the University of Bologna gave an estimation of 3.72 x 10^13, which I find agreeable with my personal calculations. Recommend changing this stat from 100T to 50T and citing the Univ Bologna study: http://nanoimmondizia.ge.ibf.cnr.it/UserFiles/documenti/Bianconi_AHB_2013.pdf
  • restructure according to the structure recommended in Wikipedia:WikiProject Science.
  • Merge with text from NCBI Science Primer User:Lexor/Temp/Cell (NCBI) is complete. Text that was not used in the article is at Talk:Cell (biology)/NCBI leftover. It is still very useful and should be merged into more specialized articles. --Lexor|Talk
  • Add information comparing the different types of eukaryotes (animals, plants, fungi, protists) and prokaryotes
  • Add information on the diversity of cell types/shapes/functions/etc, both among unicellular and multicellular organisms.
  • Protista especially are poorly represented in the article.
  • In the Organelles section, add more information about organelles in general. (Maybe some of the details about specific organelles can be removed as well.)
  • Add information (perhaps in a separate section?) on cellular dysfunction, e.g. in cancer.
  • Add information on cells in the context of biological organization
  • Add information on cell biology, on the model systems used (e.g. E. coli, S. cerevisiae, HeLa cells), etc
  • Add information on other basic cellular processes (e.g. absorption/secretion, cell signalling, intracellular transport); also refer briefly to more specialized functions such as electrical conduction
  • Fact check these points:
  • multicellular organisms have cells that "do not generally survive" when separated. Can't most plants do that? Or sponges?
    • plants: as a rule, no. certain multicellular organisms are better characterized as a collection of unicellular organisms given their lesser degree of specialization. in general, multicellular organisms have specialized cells for a reason and cannot reproduce via budding.
  • in the "cytoplasm" section, it says that all eukaryotes have cytoskeletons and implies that no prokaryotes do. Can someone confirm this?
    • prokaryotes have a cell wall to lend structural support, so their version of the cytoskeleton is not the same.
  • Are the distinctions between prokaryotes and eukaryotes as clear as they should be? Is everything about the prokaryotes right?
    • short answer: no.
  • can the line about "prokaryotic cells have three architectural regions..." be improved?
  • Is the prokaryotic cytoplasm more "granular" than in eukaryotes? Both kinds have ribosomes floating around...
  • Is the typical cell size 10 micrometers diameter, or is it the radius?
    • number given is an order of magnitude observation estimation
  • The largest observed single undivided cell is NOT the ostrich egg, but a slime mold at approximately 30 square metres.
  • Clarification needed.
 Article on cells: "Humans contain about 10 trillion (10[superscript]13) cells."   Article on Red Blood Cells: "Adult humans have roughly 2–3 × 10[superscript]13 (20-30 trillion) red blood cells at any given time,
 comprising approximately one quarter of the total human body cell number."99.65.214.26 (talk) 00:30, 15 March 2012 (UTC)

November 2015[edit]

@Iztwoz: explanations for my edits are in my edit summaries. I could also describe how we don't have nearly the strength of sources that would be necessary to support a new category of life... Sunrise (talk) 20:30, 22 November 2015 (UTC)

Apologies - hasty revert - have restored your versions. --Iztwoz (talk) 20:40, 22 November 2015 (UTC)
Thanks very much. :-) Sunrise (talk) 23:16, 22 November 2015 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Cell (biology). Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

As of February 2018, "External links modified" talk page sections are no longer generated or monitored by InternetArchiveBot. No special action is required regarding these talk page notices, other than regular verification using the archive tool instructions below. Editors have permission to delete these "External links modified" talk page sections if they want to de-clutter talk pages, but see the RfC before doing mass systematic removals. This message is updated dynamically through the template {{sourcecheck}} (last update: 15 July 2018).

  • If you have discovered URLs which were erroneously considered dead by the bot, you can report them with this tool.
  • If you found an error with any archives or the URLs themselves, you can fix them with this tool.

Periodic table[edit]

What chemical elements of the periodic table are cells made of? This article does not mention this information. --Wyn.junior (talk) 20:58, 8 March 2018 (UTC)

Where is DNA?[edit]

User has already been asked not to use article talk pages for general discussion about the subject. Adrian J. Hunter(talk•contribs) 12:27, 8 January 2019 (UTC)

In article; Some eukaryotic organelles such as mitochondria also contain some DNA.

What organelles? I can't see it under Organelles or with Wiki search.

(And I couldn't get Google to tell me either.)

MBG02 (talk) 12:38, 7 January 2019 (UTC)

Take another look at Organelle#Types and the articles Mitochondrion and Plastid. Plantsurfer 14:45, 7 January 2019 (UTC)
Thanks but I still can't get it. Is there DNA in any of; Ribosome,Vesicle, endoplasmic reticulums, Golgi apparatus, Vacuole, Cytosol, Lysosome, Centrosome, Cell membrane?
(I removed that category line you added; I presume accidentally.)

each cell type has a protein differentiation factors, protein on membrane, protein on nucleus membrane, interacting with other cells cytokines, protein proliferation factors--Axon-x (talk) 20:33, 31 January 2019 (UTC)

Why glycans aren't mentioned?[edit]

This article says "Every single cell in the human body is covered with a collection of glycans", and that they are a very important part of the cell, yet this wiki article doesn't mention glycans at all. Yurivict (talk) 04:02, 11 February 2019 (UTC)

Semi-protected edit request on 24 March 2019[edit]

Please change "humans contain more than 10 trillion (1013) cells." to "humans contain more than 37.2 trillion (3.72 × 1013) cells."

According to this research 10 trillion is a common mistake that has no trusted reference and the new estimation is 3.72 trillion.
