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.
