If a seed is lucky, it will land on good soil. When the conditions are
right, it may grow into a new plant. This is called germination. Seeds contain
their own energy store.
They do not need light at first. But they do need water, warm temperatures, and oxygen. If a
seed has the right conditions, it grows a root. The root pushes down into the soil. Then it grows a shoot. The
shoot pushes up through the soil. When
it reaches the air, its new leaves uncurl. At this point, the seed can use its
leaves to trap energy from the Sun. It does not need its own energy store any
more. Now, it carries out photosynthesis. This will help it grow into a strong,
full-grown plant.
