(ō′vyo͞ol, ŏv′yo͞ol)
A small part in a seed-bearing plant that becomes a seed after its egg cell has been fertilized by a male cell. See more at flower.


A structure inside a plant ovary containing female gamete. It develops into seed after fertilization.

'sports' are extremely rare under nature, but far from rare under cultivation; and in this case we see that the treatment of the parent has affected a bud or offset, and not the ovules or pollen.
'sports' support my view, that variability may be largely attributed to the ovules or pollen, or to both, having been affected by the treatment of the parent prior to the act of conception.
These remarks are of course confined to the first appearance of the peculiarity, and not to its primary cause, which may have acted on the ovules or male element; in nearly the same manner as in the crossed offspring from a short-horned cow by a long-horned bull, the greater length of horn, though appearing late in life, is clearly due to the male element.
The colour was caused by little gelatinous balls, about the fifth of an inch in diameter, in which numerous minute spherical ovules were imbedded: they were of two distinct kinds, one being of a reddish colour and of a different shape from the other.
In the case of the prawn-like crabs, their movements were as coinstantaneous as in a regiment of soldiers; but this cannot happen from anything like voluntary action with the ovules, or the confervae, nor is it probable among the infusoria.
Au sein du laboratoire de technologie avancee pour la reproduction animale et de recherche biotechnologique, Avantea Centre en Italie, l'equipe du projet procedera a une fecondation in-vitro a partir de la semence de Sudan, recueillie avant sa mort et conservee dans un appareil fourni par Merck, avec les ovules des deux femelles.
The key feature of an angiosperm is 'angio-ovuly' -- the presence of fully enclosed ovules, which are precursors of seeds before pollination.
torvum crossing were produced by in vitro embryo rescue from the seeds or underdeveloped ovules. Pollen viability and germination of the 50 interspecific hybrid genotypes were examined.
The former occurs when a nectar-seeking bee careens around a flower, accidentally kicking up a little dust, so that pollen is transferred from the flower's anthers to its ovules, and fertilization can proceed to generate seeds.
In contrast to living Chloranthaceae, the gynoecium consists of two to five fused carpels, but the ovules are pendent and orthotropous.

In alfalfa, the ovary of the flower has 12 ovules and tripping of its flowers is a prerequisite for pollination/seed set [42].
