Think about a garden. It is filled with plants that have flowers. How did they get there? What makes a flower grow?
First, there is a seed. The seed is hard on the outside. That keeps what is inside nice and safe. Inside the seed is a baby plant. There is also food for the baby plant.
Next, the seed is put in the ground. Water and sun make the ground wet and warm. The food inside the seed gets soft. The baby plant uses it. Soon, the baby plant grows roots. The roots are like arms that reach down into the ground to look for more food and water.
The food and water make the baby plant grow. Then, it can push out of the top of the seed. The baby plant goes up, up, up to get out of the ground. The roots stay down in the ground. They find more food and water for the plant.
Now the plant is above the ground. It is not a baby plant. It starts to make its own food. Its leaves take in sun and air. This turns into more food for the plant.
After the plant grows, it makes a flower. Then, the flower makes new seeds. Those seeds can grow new plants. Soon, there is a whole garden of plants and flowers!
