- noun Botany A structure in seed plants that consists of the embryo sac surrounded by the nucellus and one or two integuments and that develops into a seed after it is fertilized.
- noun Zoology A small or immature ovum.
from The Century Dictionary.
- noun A. little egg: specifically, in anat., physiol., and zoology, an ovulum or ovum, especially a small one, as that of a mammal, or one not yet matured and discharged from the ovary: specifically applied by Haeckel to the ovum or fertilizable but unfertilized egg-cell of the female, conformable with the use of spermule for the male sperm-cell. Its protoplasm is termed by him ovoplasm, and its nucleus ovococcus.
- noun In botany, a young or rudimentary seed; a peculiar outgrowth or production of the carpel which, upon fertilization and the formation of an embryo within, becomes the seed.
- noun Some small body like or likened to an ovule: as, an ovule of Naboth. See

- noun The rudiment of a seed. It grows from a placenta, and consists of a soft nucleus within two delicate coatings. The attached base of the ovule is the hilum, the coatings are united with the nucleus at the chalaza, and their minute orifice is the foramen.
- noun An ovum.

from The American Heritage® Dictionary of the English Language, 4th Edition
If the ovary is split open, within it will be found a little body called an ovule, which is to develop into a seed.
These, as in Gymnosperms, are of two kinds, microspores or pollen-grains, borne in the stamens (or microsporophylls) and megaspores, in which the egg-cell is developed, contained in the ovule, which is borne enclosed in the carpel (or megasporophyll).
The ovule is a part of every ovary just as the pollen is a part of every anther.
The two sperm cells enter the ovule - in the ovule are a diploid cell called the polar nucleus and a haploid female gamete
He can be told that "ovule" means little egg, and that the seed of the plant is the egg of the plant, which hatches -- sprouts -- into the plant we see.
Everything tends to prove that the ovule which is not immediately impregnated, must have an equal, if not a longer life power than the semen which is deposited in the genital parts.
"ovule" means little egg; later, a word almost identical will be used for the eggs of animals.
I keep seeing an ovule and several sperms in there –
Inferred ancestral features include more than two whorls (or series) of tepals and stamens, stamens with protruding adaxial or lateral pollen sacs, several free, ascidiate carpels closed by secretion, extended stigma, extragynoecial compitum, and one or several ventral pendent ovule (s).
Pollination in angiosperms and gymnosperms is the process that transfers pollen grains, which contain the male gametes (sperm) to where the female gamete (s) are contained within the carpel;  in gymnosperms the pollen is directly applied to the ovule itself.
