A tiny seed holds the dream of a tall tree
How do plants grow?
Today we are plant detectives: watch seeds sprout, find the secrets of roots and stems, and discover plants chasing the sun.
🌱 Sprout🌿 Roots☀️ Sun🍃 Eat
STOP 1 · LOOK AT THE SEED5 min
Open a soaked bean and look inside
A tiny baby plant is sleeping inside the seed.
The little life that will sprout.
Its first meal while sprouting.
Small as it is, the seed packs both food and a baby plant.
STOP 2 · WHAT IT NEEDS6 min
Give it three things and it wakes up
What three things does a seed need to sprout?
💧 Water: softens the coat💨 Air: to breathe🌡️ Warmth: not too cold
What happens if a seed sits in water with no air?
STOP 3 · ROOTS AND STEMS6 min
One reaches down, one grows up
Roots and stems each have a job.
Anchor the plant and soak up water and nutrients.
Carry water to leaves and hold the plant up.
Handle roots carefully when transplanting; broken roots mean no water.
STOP 4 · TOWARD THE LIGHT6 min
Why do sprouts on the windowsill lean toward the window?
Plants grow toward the light.
Plants on the windowsill lean outside because?
STOP 5 · LEAF FACTORY6 min
Animals eat; leaves make their own food
Leaves use sunlight, water, and air to make their own food.
The leaf's energy source.
Sent up from the roots.
Taken in through tiny holes.
So care for leaves—they are the plant's little kitchen.
STOP 6 · PLANT IT5 min
A tiny experiment you can do at home

① Soak: soften the bean② Place: on damp cotton③ Water: a little each day④ Watch: record how it changes
Task: observe for a week and draw how it looks each day.

You are a little botanist now
Seeds sprout with water, air, and warmth; roots drink, stems carry, and leaves make food in sunlight.
Water, air, and warmth.
Plants grow toward the sun.
Tonight, soak some mung beans and start your one-week observation.
