Water wakes it up
The seed takes up water. Keep its growing medium moist, with air spaces, rather than waterlogged.
LITTLE QUESTIONS / GROWING THINGS
Let’s grow
a little bean.
A little care. A little patience. A lovely surprise.
A bean seed contains a tiny plant and stored food. With water, oxygen and suitable warmth, it germinates: the first root emerges, a shoot grows upwards, and later the true leaves open and make sugars in light.
OUR LITTLE GARDEN
We’re peeking through the pot to see our seed.
First, water the seed. Then we’ll fast-forward through its first growth.

How does a bean seed grow?
A bean seed contains a tiny plant and stored food. With water, oxygen and suitable warmth, it germinates: the first root emerges, a shoot grows upwards, and later the true leaves open and make sugars in light.
- Germination starts with stored food
- A common bean takes up water and uses oxygen to release energy from food stored in its cotyledons, the two seed halves. Suitable warmth is also needed. It can begin germinating without light.
- Root, shoot, seed leaves, true leaves
- The first root emerges before the shoot appears above soil. In a common bean, the arched young stem lifts the cotyledons above the soil. The stem straightens, the cotyledons open, and the first true leaves develop. Other plant species can germinate differently.
- Leaves make sugars; roots take up water
- Green leaves use light, water and carbon dioxide to make sugars through photosynthesis. Roots take up water and minerals. Keep the growing medium moist with air spaces rather than waterlogged.
- The story compresses days
- Watering introduces the illustrated sequence. The animation is not a watering simulation or a prediction of daily growth. Real seeds develop at different rates, and the pot cutaway reveals parts normally hidden by soil.

WHAT HELPS A BEAN BEGIN?
A little water. Air. The right warmth.
Air matters, too
The living seed uses oxygen to release energy from its stored food as it grows.
Light helps leaves
A common bean can start germinating without light. Once leaves open, give the seedling light for healthy growth.
TAKE THE WONDER OFF SCREEN
Meet a real little seed.
With a grown-up, place a bean against the side of a clear cup with damp kitchen paper. Leave air space and keep the paper moist, not flooded. Look each day for the first root, then give the emerging seedling light.
Draw what you see. Yours may look different from our model—and that’s part of observing a living thing.
