Definition of ovule in English:
1.1 Botany The part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed.

- It is well known that most flowering plants produce more ovules than the number of seeds they mature.
- Once the pollen has fertilized the egg cell contained within the ovule, the ovule develops into a seed, and the ovary of the enclosing carpel begins to enlarge and ripen, forming the fruit.
