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.
Keywords
Seed - The development stage in the growth of a plant's offspring.
Fruit - The ripened ovary of seed-producing plants; it can be fleshy or dry.
Embryo - A development stage in the growth of a new offspring, in a plant it is formed inside a seed.
