ovules
Seeds before pollination
Ovules are the structures in seed plants that develop into seeds after fertilization.
Each ovule contains the egg cell and is enclosed within the ovary of a flower.
In botany, understanding ovule development is essential to plant reproduction: The ovules were visible when we dissected the flower.
In anatomy, ovule sometimes appears as a diminutive term for a small egg or egg-like structure.
