Article Grading: The following comments were left by the quality and importance raters: (edit ยท refresh) rated top as high school/SAT biology content - tameeria 14:55, 17 February 2007 (UTC) This article is very animal-centric. It needs a section on egg cells in plants and algae, e.g. ova production in oogonia and female gametophytes. - tameeria 19:29, 18 February 2007 (UTC) |

New research (Nature, around March? 2004) doubts if all ova are already present at birth. In case of a mouse, they found that also bone marrow can provide predecessors of ova. When they destroyed all ova, and provided new bone marrow of a donor, the mice could recover the ovary and new ova appeared. Probably they moved through the blood. It is unclear if the same is possible for human beings. Also it is unclear of these ova can become embryo's. -- July 2005
Is it just me, or is the latin origin of the word ovum explained twice in the first paragraph? --IronChris 03:35, 31 March 2006 (UTC)
- Yes, it is. Someone should do something about that. --Romarin 04:37, 31 March 2006 (UTC)

- Done. --Romarin 04:46, 31 March 2006 (UTC)
[edit] Simpler
Would it not be smarter to make the introduction simpler?--Filll 10:36, 10 December 2006 (UTC)
An ovum (plural ova) is a haploid female reproductive cell or gamete.
- haploid? awkward definition of gamete.
The word is derived from Latin, meaning egg or egg cell.
- could be worded better
Both animals and embryophytes have ova.
- embryophyte?
The term ovule is used for the young ovum of an animal.
- not quite sure what this means.
In some plants, such as algae, it is also called oosphere.
- what about trees? This sentence is awkward.
These are my comments for whatever they are worth,--Filll 18:14, 13 December 2006 (UTC)
