The mother plant sends the baby seed away with a packed lunch. This means the seed will have enough energy to start germinating, until he has made his own leaves which will supply him with more energy to grow into a big healthy plant.

In order for a seed to germinate, the temperature must be right and there must be water to soak the seed. Some seeds also need light. If all the seed's needs are present, it will start to grow. The food reserves are turned into a form the plant embryo can use for energy to grow. First, the root (radicle) emerges from the seed coat, followed by the shoot (plumule). The root always grows downwards into the soil, while the shoot always grows upwards towards the light .

Leaves begin to grow so the plant can obtain energy from the sun. The bigger seeds are, the longer the seedling has to become properly established before it must make its own food. Small seeds, with few food reserves, must grow and reach the light quickly, so that they can start producing their own food.
