2007 comments on merge

ALTERATION OF GENERATIONS

1.SPOROPHYTE GENERATIONS

2.GAMETOPHYTE GENERATIONS

Would it not be better just to merge this and sporophyte into alternation of generations?

No, because organisms with a haploid-dominant life cycle also have gametophytes.--Curtis Clark 04:04, 12 July 2007 (UTC)[reply]

I suggest changing the link ovule to just ovule. Bayle Shanks 02:06, 12 July 2007 (UTC)[reply]

"Gametophycation"

This seems dubious, and desperately needs supporting citations. See Wikipedia talk:WikiProject Plants#Gametophycation. Guettarda (talk) 07:21, 19 April 2009 (UTC)[reply]

Seed Plants

Hi, I have noted that the seed plant section of this page could use a little more information. It is currently only two sentences. In the heteromorphy section, there is a little more information, but I think it could be expanded upon and moved to the seed plant section of page. Feel free to respond here if you have any thoughts about this. 19345beta (talk) 19:36, 31 October 2020 (UTC)[reply]

As I have been researching the seed plant gametophyte, I think it is important to separate gymnosperms and angiosperms into separate sections. Does anyone have an opinion about creating two subsections? 19345beta (talk) 00:27, 17 November 2020 (UTC)[reply]

@19345beta: I'm not sure about separate sections: the article is very subdivided as it is, but it is clearly right to say more about these two major groups and their similarities and differences in relation to gametophytes. Peter coxhead (talk) 07:22, 17 November 2020 (UTC)[reply]

I appreciate the input. I think I might try to have 2 paragraphs about angiosperms (male and female) and the same with gymnosperms for 4 total paragraphs but not subdivide the page any more so they will both be under the 'seed plant' header. I am writing a draft which is on my sandbox User:19345beta/sandbox that if anyone wants to look at and comment, please feel free to do so in the sandbox or here. 19345beta (talk) 18:11, 6 December 2020 (UTC)[reply]

After consideration, I have decided to leave the heteromorphy section unchanged. It does provide a more rudimentary discussion of seed plant gametophytes that may be of use to some readers. If there are any comments about this please let me know. I have also added the text from my sandbox to the actual page. Please feel free to comment or edit here or in the main article as needed. 19345beta (talk) 02:57, 17 December 2020 (UTC)[reply]

Nucelli/Nucelus

The article uses "nucellus" without defining it anywhere, and at least some occurrences are not consistent with the definitions I can find, e. g. "In some Gnetophyta species, the germ cell will release two sperm nucelli ..." However, the Free Dictionary defines "nucellus" as "The central portion of an ovule in which the embryo sac develops." (https://www.thefreedictionary.com/nucelli) Obviously, this would not be consistent with "sperm nucelli." Was the original editor using it as a synonym for "nucleus"? IAmNitpicking (talk) 01:25, 19 December 2020 (UTC)[reply]

Hi. Thanks for the comment. I noticed a few things after going back that I now realize need attention. First is that I was using nucelli, nuclei, and nucleate as pretty much as synonyms, really all the nucelli should be changed to nuclei to specify they are in relation to the cell organelle - the nucelus, the organelle holding the genetic material. This is important for referencing free nuclei. It was false to use nucelli as you mentioned. Further, after reading the example you used, I realize that the sentence makes it seem like the nuclei exist on their own with nothing else in the selected Gnetophyta species referenced. This is not true, the two nuclei are free nuclei but they are not completely alone. I will think about how to state this clearer and will clean both of these issues up in a few days unless someone else gets to it before me. I will make another comment on this talk page when this happens 19345beta (talk) 05:31, 23 December 2020 (UTC)[reply]

Another editor went through and changed the nucelli to nuclei so that is now fixed. I looked over the two papers, currently reference 8 and 11 and am unsure how to better edit the sentence, hoping someone here will have an opinion. In some Gnetophyta species, the germ cell is binucleated. The nuceli are never not part of a cell (my fear is that the sentence makes it seem that way). However it is true that double fertilization occurs without full cells and just the two free sperm nuclei do the double fertilization. Let me know if you think it reads that way or if the common reader might get confused with that sentence. 19345beta (talk) 00:05, 26 December 2020 (UTC)[reply]

There is no cell organelle called the nucelus. There is an organelle in eukaryotes called the nucleus, however. Plantsurfer 19:17, 29 April 2022 (UTC)[reply]
