ovule Structure that will become a seed following fertilization; literally an integumented megasporangium that contains the embryo sac before fertilization.
Self-incompatibility
Most angiosperms have mechanisms by which they avoid self-fertilization. Link to a discussion of these.
Seeds
After double fertilization, each ovule develops into a seed, which consists of ...
The shape of the ovules as they develop often affects the finale shape of the seeds. Plants generally produce ovules of four shapes: the most common shape is called anatropous, with a curved shape.
The process of pollination being accomplished, the pollen tube grows through the stigma and style toward the ovules in the ovary. The germ cell in the pollen grain divides and releases two sperm cells which move down the pollen tube.
(Science: botany) a flowering, fruit-bearing plant or tree, the ovules (and therefore seeds) of these plants develop within an enclosed ovary. Plants having seeds in a closed ovary.Pertaining to plants that contain seeds enclosed in the [[ovary.
nucellus. In plants, the watery tissue composing the chief part of the young ovule in the flower and inside the seed during early development. It furnishes nutrients to the young embryo and is digested by the developing endosperm and embryo.
Plants make pollen in the stamens (male parts) and ovules in the ovary (female part). There are many variations on this basic theme of making male and female gametes.
seed - reproductive unit formed from a fertilized ovule, consisting of embryo and seed coat, and in some cases an endosperm (Glossary of PM) ...
Their ovules are enclosed in the carpel and pollen travels through the pollen tube to reach it. Angiosperms evolved in the Cretaceous era together with the Mammals. Angiosperms in Tree of Life.
