Historical Examples of ovule
The ovule or egg is now in the cavity of the womb where we will leave it for the present.
We have seen that the ovule from the ovary is the female egg, or principle.
Before a child is possible, however, the ovule must meet the egg from the male.
The ovule is a part of every ovary just as the pollen is a part of every anther.The Renewal of Life; How and When to Tell the Story to the Young

Word Origin for ovule
1821, from French ovule and directly from Modern Latin ovulum, literally "small egg," diminutive of Latin ovum "egg" (see ovum).
- A small or immature ovum of a mammal.
- A small egglike structure.ovulum
- The female reproductive structure that develops into a seed in a seed-bearing plant. An ovule consists of a megasporangium surrounded by one or two layers of tissue called integuments. The megasporangium produces spores that develop into megagametophytes. These megagametophytes remain within the tissues of the ovule and produce one or more egg cells. Sperm from pollen grains enter the ovule through an opening called a micropyle and fertilize the egg cells. The resulting embryo then begins to develop within the ovule, which becomes a seed. Among the conifers and cycads, the ovules are typically found in pairs on scales in the female cones. The ovules of angiosperms are contained in a structure called the ovary within in the flower.
