Parts

Roots
The roots grow at the very bottom, thin and tangled like little threads. They drink water from the soil and hold the plant up so it does not fall over.
Stem
The stem stands between the roots and the leaves and holds the whole plant up. The water the roots drink travels up inside it, all the way to the top.
Leaves
The leaves are big and wide, like little fans. They take in sunlight and air and make food for the whole plant.
Flower
This is the flower, with petals all around the outside and a soft middle. After the petals drop, seeds grow in that middle.
Petals
The petals ring the middle in a bright yellow circle. Their colour calls the bees to come and visit.
Seeds
Row upon row of seeds grow in the middle, and every seed has thin stripes. Ripe seeds can be eaten, or planted to grow new sunflowers.
Seed head
When the seeds are ripe, the middle becomes a round head packed with them. The petals drop off, and the heavy head bends down low.

See how it works

Grow

  1. The roots drink water first. Then a small green shoot pushes up out of the stem.
  2. The stem grows taller day by day, and new leaves open along it.
  3. A little bud appears at the top. When the bud opens, out comes a ring of yellow petals.

Follow the sun

  1. In the morning the sun is in the east, so the flower faces east and opens all its petals.
  2. All day long the stem slowly bends, and the flower follows the light across to the west.

Make seeds

  1. The petals fade and drop off, and the middle swells up with rows of seeds inside.
  2. The seeds grow plump and the head turns heavy. It bends down low, and now the seeds are ripe.
