Talk:Plant embryonic development

message: Hello! I am a college student currently enrolled in a seed plants course. Our assignment, focused over the course of the semester, is to edit a Wikipedia article. I have chosen this one as part of my assignment. I feel there is a lot more information on this topic that can be added to this article. I plan to flesh out the lead section and give it more substance. Then I plan to create a new heading called "Morphogenic events." Here I would include subheadings on each of the individual embryogenic stages including the two cell stage, eight cell stage, sixteen cell stage, globular stage, heart stage, and torpedo stage. I have a great deal of information on the two cell and eight cell stage. I am lacking on information from the other stages, but I plan to change that! I believe the plant growth and bud section talks about embryonic tissue than actual embryogenesis, but I think it is okay as is. Next, I plant to add a heading entitled "The role of auxin." After reading two articles on the topic, I could tell this hormone is crucial to plant embryogenesis. However, there is already a Wikipedia page dedicated to it, so I will not go into too much detail. Another heading I would add is "Dormancy." There is already a Wikipedia page dedicated to dormancy. However, it does not focus solely on plants. It covers both animals and plants, discussing why it is beneficial for survival. Dormancy would be beneficial to this article because there are two main stages to plant embryogenesis - morphogenesis/maturation and arrested development. In the literature I have gone through so far, it states that the arrested development stage and the dormancy aspect of plant embryogenesis are almost one in the same. Therefore, I would give information about dormancy and show it is beneficial in embryogenesis. Lastly, I plan to make a heading entitled "Alternative forms of embryogenesis" including information on somatic embryogenesis and androgenesis. The portion on somatic embryogenesis I plan to shorten, because there is already a Wikipedia article dedicated to it. I plan to include a short paragraph about androgenesis, and how a fully fledged embryo can form from just one pollen grain. I thought that was very interesting. The beginning stages are different, but near the end the process is the same as regular plant embryogenesis. I would put more information about this topic, or maybe even start a new page on it, but there is not enough research done yet. Here are the sources that I have found beneficial to my research so far:

I plan to start moving my edits to Wikipedia within the next week. I would be grateful to have feedback on what I have presented here. Questions I have: Are there any errors I am making?

thread_title: 2018 Spring Semester College Assignment

message: This article is going from bad to worse. The wording, phraseology and recent edits make it extremely hard to understand. It urgently needs cleaning up and the use of more clear less obscure phrasing to improve it. It is a big mess. Peter morrell 08:55, 25 July 2008 (UTC)
thread_title: Dreadful wording

message: A casual reading of this article seems to imply that plant embryogenesis is a process which only takes place for seed-bearing plants. There is no mention of ferns, marchantiophyta, or anthocerotophyta by either their scientific or common name. The definition that "Plant embryogenesis is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo." seems to also imply this because ovules are only found in spermatophytes (according to the Wikipedia entry). My suspicion is that the process is generalizable to non-vascular plants but it is possible that this is the true definition. I don't know for sure. In any case, clarification is necessary.
