Lesson Details
Key learning points
- Seeds contain an embryo, food store and a tough outer coat, and they are formed in the ovary.
- A fruit is the mature and ripened ovary of a seed-producing plant.
- Fruits often contain seeds which will grow into a new plant, given the right conditions.
- Seeds are adapted to be dispersed by animals, wind and water.

A seed is not living.
A seed is living, it contains an embryo and a food store and is a stage of development in the growth of offspring.
