The tubules deliver the spermatozoids, which were formed in the pollen grains, either before pollination (in plants with tricellular pollen) or afterward, with the division of sperm cells in the pollen tubules (if the pollen is bicellular).

The female gametophyte—specifically termed a megagametophyte —is also called the embryo sac in angiosperms. The megagametophyte produces an egg cell (or several egg cells in some groups) for the purpose of fertilization.

Fertilization, development of an embryo, and conversion of the ovule into a seed become possible after pollination, that is, after the entry of male game-tophytes (pollen grains) into the micropyle of the ovule in gymnosperms or placement on the stigma in angiosperms.

In some plants, however, integuments are absent. In the morphological classification of ovules, consideration is given to the position of the micropyle and the longitudinal axis of the nucellus in relation to the funiculus.

Location within the plant [edit]. In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a funiculus (plural, funiculi). Different patterns of ovule attachment, or placentation, can be found among plant species, these include: 1  Apical placentation: The placenta is at the apex (top) of the ovary.

in seed plants, a multicellular formation from which the seed develops. The principal parts of the ovule are the nu-cellus, the integument (or integuments), and the funiculus. The nucellus typically develops as a nodule of placental cells of the megasporophyll, or carpel.

When ripe pollen from an anther of the same kind of flower catches on the stigma, each pollen grain sends out a tiny threadlike tube. The tube grows down through the style and pierces one of the ovules in the ovary. This process is called fertilization. Each ovule must receive the contents of the pollen tube before it can develop into a seed. It usually takes the tube from.
