Step 1 of 4
- A dry moong seed. It looks still.
- Give it water, warmth and air.
- A root and a shoot appear. It has germinated, or started to grow.
- Later, the leaves use sunlight to make food.
The rule
The seed does very little, but it is alive.
Every living thing needs food and air, again and again.
- An animal eats its food.
- A plant makes its own food, using sunlight.
- Both need air.
A resting seed is dormant. It is alive, but waiting for water, warmth and air. When a root and shoot appear, the seed has germinated. The shoot is the part that grows up.
